You know what I think you get scared of more - especially me, after touring for so long and being in bands for so long - you start to associate certain behavior with the music. It's like people associate having a cigarette with having a cup of coffee, or lunch.
I don't care if it's rap, metal, whatever. You still should play Beatles records mixed with Limp Bizkit mixed with Foghat mixed with Creedence Clearwater Revival, stuff like that.
