Apple Raises iTunes Match and Apple Music Library Matching Limits to 100,000 Tracks
Just ahead of the launch of Apple Music in late June, Eddy Cue revealed on Twitter that Apple was working to raise the matching limit from 25,000 tracks to 100,000 for iOS 9, but the increase did not occur in September when iOS 9 debuted.
MacRumors checked with Cue back in October for an update, and he indicated Apple was "definitely working on it" with the expectation the increase would go live "before the end of the year."
Apple has yet to update its support page on uploading music Apple Music to document the new limit.
Update 12:08 PM, December 6: Eddy Cue has confirmed to MacRumors that Apple has indeed "started rolling out support for 100k libraries."
