In one of my previous bands, I wanted to play some songs that were hard for the drummer, other songs hard for the bassist, other songs that's not of their musical taste... So usualy when I get into such a situation (I've been already there quite a lot, lol) , I loose interest in the band & just quit.
There's nothing better beeing in a band with similar musical taste & technical level... and hopefully nice people to enjoy working with them.
