A PeRfeCt CirCle, NiRvAnA (sort of hard to stay a hardcore fan when the band has moved on, but was my first favorite band), TooL, WhiTe StRiPes, well that's about it. I have tons of songs that I like, I like a lot of rap, but A PeRfeCt CirCle and TooL are bands that I can just throw the c.d. in and listen all the way through.
