I purchase all my music through iTunes, yet I can never get the genius feature to work on my iPhone 4s.
Whenever I press the genius button in the music player it says "This song does not have enough related songs to create a Genius Playlist".
But with 15gb of music all from the iTunes store I'm doubting this.
For example it says this with Skrillex's new album, but there are at least half a dozen other albums in the same genre that it should easily be able to find.
Any ideas?
