Has anyone messed around with Beatles songs on iTunes genius? When I first installed iTunes 8 and started playing with Genius, I immediately noticed that if I tried using a Beatles song, it said Genius was not available for that song. I figured (and still do) that it had something to do with the iTunes store not currently carrying the Beatles catalog. I tried it again recently and it is now working when I used Beatles songs as the root (hooray!). However, if I use a song from a band where I would expect one or two Beatles songs to show up in a Genius play list, they never do. I've tried it by using the same songs that show up in when I used a Beatles song as the original and hit refresh over and over, but they never pull from my Beatles catalog.

Any thoughts?
