I mentioned during the A to Z that I enjoyed Nirvana's album Bleach. Listening to it again though I realized that there aren't as many tracks that I knew. Still though, it's a reasonably solid album that has a lot of good songs.
Negative Creep is one of my favorite songs on the album, and I would advise you listen to it.
I hold by what I said before though, Nirvana is a very overrated band.
