I didn't even like music as a tween, but as an early teen I got into it, here is my teen life in terms of music.

Just turned 13; My chemical romance, sum 41, the offspring, mostly anything my brother listens to.
13-14: Marylin Manson. End of Story.
14-15: Jack off Jill isn't bad. Marylin Manson is still god though.
15-17: Jack off Jill > Marylin Manson. Scarling is also pretty good, and I'm just hearing about Nightwish.
17-18: Marylin Manson is old and tired. jack off Jill is 'meh' but Nightwish is EVERYTHING.
18-19: Broadway musicals pwn. Chicago, Rent, Wicked, all pure love.
Now nearing 20; anything Pagan, and broadway is love, most country and rock is good, and some pop isn't half bad if I ignore the artists who perform them.
