Around 12. I heard Nirvana, and it started from there.

Although, I still do enjoy Britney.

i was 11 when i started listening to stuff like linkin park & korn
ok, they're ****, but from there i got into bands like nirvana & hole

when I was 11 and Nirvana stole my heart.

I did it a bit backward. At 11/12 i loved the Pumpkins, Tori Amos, Garbage, Alanis Morissette. Got into Hole, BiT etc when i was about 15. I listen to more pop than i ever have now at 22. I still listen to other stuff too though. I'm going to see the Dresden Dolls in september, two days later i'll be seeing the Rogue Traders haha.

When i was about 13ish i started listening to indie. I have those indie compliation cds to thank a lot for. Then it went on from there ..
