First CD I ever bought... no kidding, I didn't get a CD player until I was seventeen... catchy riffs, driving rhythms, both radio hits and more punkish favorites. If you're hardcore punk, you might think this was a pop album, but tracks like Genocide and Killboy Powerhead are as non-pop as it gets. I don't think I can really even say I Like those songs' level of punkishness (I don't like "real" punk much, I think it gets a little inane at times) but the rhythms get in your head.
