Apple’s music streaming service will be able to scan and match up to 100,000 songs, up from the previous 25,000 with iTunes Match. Back in July following the release of Apple Music, Eddy Cue confirmed that they are working on getting the match limit increased by the release of iOS 9. Now that iOS 9 has been out for a few weeks, MacRumors tweeted to Eddy Cue to get the details and he confirmed that they are working on raising the limit “before the end of the year.”
Prior to Apple Music iTunes Match has been used to scan all the tracks in someones iTunes library, compare it to the iTunes catalog and push it to other devices. iCloud Music Library works in a similar way, although its used to sync new music and playlists to other devices.
