Mine was "Sex Type Thing" on Expert Pro Drums for a LONG time, until recently. It changed to "Aerials", same instrument.
"Most Played Genre" - does it just pick artists @ random in that category? Mine shows The Hives and Jet, and I rarely play those songs.
Mine continues to be Sex Type Thing by STP on expert Pro Drums, and has been since the moment my Pro Drum score overtook my legacy guitar score, oh, something like a year ago. A fact I find interesting concidering I KNOW I've FC/gold starred much harder and higher tiered songs on Pro drums. I'm not sure how it all works, but I'm guessing your rank on a song must be figured in somewhere? Not that I'm complaining. I love Sex Type Thing and STP.
But I believe in this and it's been tested by research: he who  nuns will later join the church.
