We all do the same thing - we learn to play songs we are interested in learning. Once you move from that to being part of a band and performing to entertain, your personal preferences of music become much less important. To do that, you need to find like minded musicians and a venue to play in that likes the same music. It's hard enough to put a band together without those limitations! :-).

I've known people who were in multiple bands so they could play music they perferred.

It sounds like Rocksmith is helping you out. "We are the Champions" is a song I should learn. The guitar work in that song is pretty cool.
