I am no Dead Head, but I like American Beauty as an album. And I like Casey Jones and Touch of Grey.
Contemporary Country - A lot of crap to wade through here. But there is the occasional good song here and there. And I love Alan Jackson, and even kind of like some of Toby Keith's music.
Rap - Not a fan of the genre. But I love Run DMC. And I agree (with some one) that OUTKAST are fun.
And Lady Gaga.
