Apple Music is a streaming service developed by Apple that gives users access to over 90 million songs. When users add songs to their Apple Music library, either by adding existing songs they own or saving songs from Apple Music’s catalog, those songs become available across all of their Apple devices through a syncing process. This syncing allows users to listen to the same music library whether they are on their iPhone, iPad, Mac, HomePod, Apple TV, or Apple Watch.
The time it takes for Apple Music to fully sync a user’s library across devices depends on several factors. This includes internet connection speed, the number of songs in the library, whether it is syncing to mobile devices or desktop devices, software updates, and other issues. Overall the process can range from nearly instantaneous to a couple hours for very large libraries.
Downloading Music
Apple Music allows you to download songs and albums for offline listening when you don’t have an internet connection. This is done through the Apple Music app on iPhone, iPad, Mac, Apple TV and Android devices. When you download a song or album, it will be saved locally on your device and available to play without needing to stream it over the internet.
Downloading music can increase the time it takes for Apple Music to fully sync across your devices. This is because the downloads are additional files that need to be transferred and synced. For example, if you download a large playlist or several albums on your iPhone, it will take longer for that new content to sync across any other devices compared to just streaming songs. The more downloads you have, the longer the initial sync process typically is.
According to Apple’s support article, downloads are prioritized in the syncing process:[1] This means downloaded songs and albums will sync first before things like playlists and your music library. So while downloads may increase sync time, they won’t get stuck behind other syncing actions.
Album vs Song Sync
There are some differences in sync times when downloading individual songs versus full albums from Apple Music. According to Apple Support, songs and albums are downloaded by touch holding the music in your library and tapping “Download.”
In general, individual songs will download more quickly than full albums. Users on the Apple Discussions forum report individual songs taking anywhere from a few seconds to a couple of minutes to download and sync [1]. Full album downloads are more variable, but can take significantly longer depending on the number of songs. One user reported an album with 14 songs taking around 15 minutes total to fully sync [1]. So the average per song for a full album is over 1 minute.
The main reason for this difference is that downloading a full album requires syncing multiple larger files rather than just one song file. Additionally, issues like unstable internet connectivity can slow down full album downloads more than individual songs. Overall, while individual songs are quite fast to sync from Apple Music, full albums may take patience to fully download.
Internet Connection Speed
The speed of your internet connection is one of the biggest factors that impacts how long it takes for Apple Music to sync your library. Users report widely varying sync times depending on if they are on 3G, 4G, WiFi, or a wired connection.
In general, 3G wireless connections are the slowest and can take days or even weeks to fully sync a large music library to Apple Music. As one user reports, “The time to completed would depend on how good your internet speed is. On 3G it will take forever” (Source).
4G LTE wireless connections are faster than 3G and can sync music more quickly. However, sync times over 4G can still take multiple hours or days depending on library size. As one user with 50,000 songs reported, it took 3 full days to sync their library over a 4G connection (Source).
WiFi and wired Ethernet connections generally provide the fastest sync times. However, even over very fast connections, Apple Music sync can be quite slow due to bandwidth limitations on Apple’s side. One user with a 920 Mbps wired connection still reported multi-day sync times, indicating bottlenecks are not only due to user connection speeds (Source).
Number of Songs
The total number of songs being downloaded is one of the biggest factors affecting how long an Apple Music sync will take. Users with larger music libraries of 10,000+ songs report sync times of 6-12 hours or longer (Discussions). Smaller libraries with just a couple thousand songs may only take 1-2 hours to fully sync.
Apple Music downloads songs at a rate of roughly 5-10 songs per minute on average broadband connections (Discussions). So for a library of 10,000 songs, the expected baseline sync time would be 17-33 hours. Faster internet speeds can accelerate this, while mobile connections and bandwidth throttling may slow it down.
The main reason the number of songs affects sync time is simply due to the total download volume required. Each song is a separate file that must be downloaded to the device, taking time. The more songs in the library, the longer the total download queue.
Users looking to reduce initial Apple Music sync times are advised to download only their most wanted songs and playlists. The full library can continue syncing in the background afterwards. Setting downloads to occur overnight or during times of low bandwidth usage can also optimize sync performance.
Mobile vs Desktop
Sync times can vary significantly between mobile devices and desktop computers when using Apple Music. According to discussions on Reddit (source), Apple Music tends to sync faster on desktop applications compared to mobile apps on both iOS and Android devices. This is likely due to the additional processing power and internet connection stability typically available on desktops.
On mobile devices, sync speed can be impacted by factors like phone model, operating system, available storage space, and internet connection quality. Larger iOS device models with more RAM like newer iPads and iPhones tend to sync Apple Music faster than smaller older models. Meanwhile, Android users report slower Apple Music sync speeds compared to iOS, sometimes excessively slow. This may be due to optimization differences in the Apple Music apps for each OS.
For optimal sync performance on mobile, users should ensure they are on the latest OS version, limit background app activity during sync, and connect to strong WiFi. However, desktop Apple Music sync will almost always be faster than mobile. The convenience of mobile comes with slower sync tradeoffs compared to the stability and speed of desktop.
Troubleshooting Tips
There are a few tips and tricks you can use to help reduce Apple Music sync times:
Connect your device to a stable WiFi network instead of mobile data. Syncing over WiFi is significantly faster than mobile networks (source).
Close any other apps running in the background on your device. Having multiple apps open can slow down sync speeds.
Make sure your devices are updated and running the latest iOS/macOS software version. Older versions may have bugs that impact sync performance.
Restart your device before syncing a large music library. This clears any memory issues and ensures your device is running optimally.
Disable iCloud Photo Library temporarily during music syncs. The photo sync can interfere with bandwidth needed for Apple Music.
If you have an iOS device, enable Low Data mode which pauses automatic iCloud backups and app updates that may conflict with Apple Music syncing.
Delete and re-download the Apple Music app if you continue having issues. This resets any corrupted files or cached data.

Software Updates
Apple regularly releases software updates for iOS, iPadOS, macOS, and iTunes to improve performance and fix bugs. These updates can impact how quickly your Apple Music library syncs across devices. Some users have reported faster sync times after updating to the latest OS and iTunes versions. However, others note issues with syncing immediately after a major software update.
For example, one user on Apple’s support forums reported their music library failing to sync properly after updating to macOS 13 (Source). Resetting sync and restarting their Mac resolved the problem. Another user had trouble syncing their iTunes library to an iPhone after updating to iOS 17, fixed by trusted the computer and updating iOS (Source).
While periodic software updates aim to improve performance, syncing problems immediately after an update are not uncommon. Allowing some time for Apple to refine the software release may lead to faster, more reliable sync. Checking for updates regularly can optimize Apple Music sync over the long run. However, expect potential slowdowns or issues immediately following major iOS, macOS or iTunes updates.
Expected Sync Times
The amount of time it takes for Apple Music to fully sync can vary based on several factors:
Syncing an album will generally be faster than syncing individual songs. When syncing an entire album, Apple Music can transfer all the song files in bulk rather than individually. According to this Apple forum thread, an album may take only a few minutes to download and sync.
Internet connection speed plays a major role. On a very fast connection of 100Mbps or higher, an album could potentially sync in under a minute. On a slower DSL or mobile connection, it may take 5-10 minutes for an album depending on size. Individual songs will sync faster on a faster connection. Based on user reports, songs can take 1-2 minutes each on slower connections.
The total number of songs or albums being synced also impacts time. Syncing a user’s entire library of songs and albums will take considerably longer than a single album. For a library of a few thousand songs, the full sync may take hours, especially on slower connections.
Syncing between a mobile device and desktop takes longer than between two desktops or two mobiles. This is because of the inherent limitations of mobile connections. Users report mobile-to-desktop syncs taking hours in some cases.
Conclusion
In summary, the amount of time it takes for Apple Music to sync depends on several key factors. The main elements are your internet connection speed, the number and size of songs or albums you are syncing, whether you are on mobile or desktop, and any software issues. On average, syncing an album takes 5-10 minutes on a fast WiFi connection. Individual songs may sync within seconds or minutes. Syncing a large library of songs can take hours, especially on slower internet speeds. Using a wired connection on desktop, updating software, syncing one album at a time, and having patience are some tips to improve sync times. While syncing can be slow, Apple Music aims to eventually make your full library available across devices.
