Because it’s overshadowed by the more widely used Apple Music, iTunes Match doesn’t get much attention. You may think that Apple Music is all you need, and in most cases that is true. But while the two services are related, they do some things differently. iTunes Match requires a paid, annual subscription. After you subscribe, the service automatically renews every year unless you cancel it.
Adding Music to iTunes Match
You can add up to 100,000 songs to your iCloud Music Library via iTunes Match, and your music goes to iTunes Match in three ways:
Music File Formats in iTunes Match
iTunes Match supports all the file formats that iTunes does: AAC, MP3, WAV, AIFF, and Apple Lossless. The songs it matches from the iTunes Store won’t necessarily be in those formats, however. Music that you bought through the iTunes Store or that is matched by the iTunes Store is automatically upgraded to DRM-free 256 Kbps AAC files. Your computer will convert songs encoded using AIFF, Apple Lossless, or WAV to 256 Kbps AAC files and then upload them to your iCloud Music Library.
High-Quality Music Files and Backups
When iTunes Match creates a 256 Kbps AAC version of a song, it only uploads that version to your iCloud Music Library. It doesn’t delete the original song, so those files stay in their original format on your hard drive. If you download one of these songs from iTunes Match onto another device, it will be the 256 Kbps AAC version. You should always back up your original music files, even though iTunes Match keeps a copy in iCloud. Making backups is particularly important for those high-quality music files you may own because if you delete the higher-quality version of the song from your computer, you’ll only have the 256 Kbps version from iTunes Match.
Do You Need iTunes Match and Apple Music?
Apple Support states that: When you subscribe to Apple Music, your music moves to your iCloud Music Library, and it will be available across all of your devices that are logged in to the same Apple ID, just as with iTunes Match.
Streaming Music From iTunes Match
On a computer, you can stream or download songs from your iCloud Music Library. Select the iCloud button next to a matched song to download that song to your computer. If you double-click to play it, the song streams without downloading. On an iOS device, playing a song causes it to both play and download, while on an Apple TV, you can only stream music.
Playlists and Voice Memos
iTunes Match supports playlists but not voice memos, even if you sync memos from your phone. Your iTunes playlists will sync to all of your devices via Match, except ones that include unsupported files like voice memos, videos, and PDFs.
Updating Your iTunes Match Library
As long as iTunes Match is turned on, it automatically attempts to add your new songs to the iCloud Music Library—you don’t have to do anything. However, to force an update to iTunes Match, select File > Library > Update iCloud Music Library.
Limits to iTunes Match and DRM
iTunes Match has a few limits other than the one restricting you to 100,000 songs. You can’t upload songs that are larger than 200 MB or longer than 2 hours to your iCloud Music Library. Songs with digital rights management (DRM) enabled will only upload if your computer is authorized to play them. Technically, it may be possible for Apple to tell if some of the music in your iTunes library is pirated, but the company has said it won’t share any information about users’ libraries with third parties, such as record companies or the RIAA who might be inclined to pursue pirates. Finally, only 10 total devices can share music on an iTunes Match account.
Canceling an iTunes Match Subscription
If you’re signed up for iTunes Match but want to cancel your subscription and you cancel your iTunes Match subscription, all the music in your iCloud Music Library—iTunes Store purchases, music matching, or uploads from your computer—stays where it is. However, you can’t add any new music or download or stream songs without subscribing again.
iCloud Music Icons
After you sign up for and enable iTunes Match, you can view a column in iTunes that shows a song’s iTunes Match status (these icons appear by default in the Music app). To enable it, select Music from the drop-down in the upper-left corner, then select Songs in the iTunes sidebar. Right-click the top row and check the option for iCloud Download. When that’s done, an icon appears next to each song in your library:
Cloud with a downward arrow means this song is in your iCloud Music Library but isn’t on this device. Click the icon to download the song.Cloud with a dotted outline indicates a song that either hasn’t been uploaded or is waiting to be uploaded.Cloud with an X means the song was removed from your iCloud Music Library by another computer or iOS device that has access to it.Cloud with a line through it signifies a song that is not eligible for iTunes Match for any number of reasons.Cloud with an exclamation point indicates that the song was not added to your iCloud Music Library due to an error. Update your library to add it again.
In the same menu, you can choose iCloud Status for a text description of each song:
Apple Music means it came to the iTunes library from the Apple Music service.Matched means either iTunes Match or Apple Music matched it to the library.Purchased appears if you bought a track from the iTunes Store.Uploaded is for songs you added from a CD or other source.Not Uploaded means the song came from another device, for example, an iPhone, but your computer doesn’t have the file.Ineligible is for songs that you aren’t allowed to play, either because a different Apple ID purchased them or they don’t fall into the iTunes Match length or size limits.Waiting means a track is in the process of uploading but hasn’t done so yet.Removed songs are on your computer but not your iCloud Music Library.
