Nirvana - "Smells Like Teen Spirit"

These guys were game changers. In an era of glam bands, they ripped apart the status quo with this song forever changing the landscape of rock music.

I still remember the first time I heard this. I was handed an insiders demo tape with some new artist. This was on there and it blew my mind, I listened to it a lot for about 3 months until it hit the airwaves, and the rest is history.
