I am considering purchasing iTunes Match, and have am looking to see if it would solve my problem. My problem is this: almost all of my music is either purchased from somewhere else other that iTunes or uploaded from CDs. Either way, Genius does not work for nearly any of them. Every time I try to use Genius I get the message "This song does not have enough related songs to create a Genius Playlist." These songs are all mainstream songs that are usually on the iTunes top charts, not obscure bands or anything like that. Does Genius doesn't work because my music is not purchased from iTunes? If so, would purchasing iTunes Match allow Genius to work better? Thank you for the help!
