Up to 100,000 songs, not including songs (or music videos) purchased from the iTunes Store; files can be no larger than 200MB
Matched songs (songs available in the iTunes Store, whether or not you purchased them there) at iTunes Plus quality (256kbps DRM-free AAC) and other songs at their original quality
Music videos purchased in the iTunes Store
Playlists that include songs and music videos
Smart Playlist rules, which are applied on the computer or device they’re downloaded to
