I like Van Halen to a degree although I'm picky on songs.(Dance the Night Away and Me Wise Magic are some those songs I really like).
I wish to be a magician of words!
I liked VH in my Beavis and Butthead years. Along with Rush and AC/DC. Kind've grown out of them. Some bands from that era I'm still into would be the likes of Sabbath, Purple, BOC, etc...
At least I didn't get my start with melodic metalcore or numetal or whatever. Poor kids these days.
More metal in Rock Band:
UO: I disagree. A lot of mainstream rap is good. Kanye, Jay-Z, OutKast, etc. are great. I would rather listen to mainstream pop over nu-metal, too. Lady GaGa and even Katy Perry are better than the drivel Linkin Park puts out if for no other reason than that they don't take themselves seriously as emotional powerhouses.
I'd rather listen to Linkin Park than any of the people R2R listed, but none of the people R2R listed are bad. Except Lady Gaga, she annoys me.
