Yes. Everyone needs to listen to Death, it'll set your music tastes straight.
Just gotta keep listening, I was told by someone, that all music can be traced back to either Jazz, Classical, or 'world' music.
Eg. to get to rock, you go: Jazz --> Blues --> Rock.
So I guess those are places to start?
at 14 I was listening to ALOT of Muse. And various Alt. rock, indie stuff. as well as Metallica and Iron Maiden. At 15 I was listening to pretty much just metal, move forward to 17 and I'm now listening to Rock, Metal (mostly prog Metal), Alt. rock, Jazz, Blues, Classical, and even a tiny tiny bit of electronica dance stuff.
Basically, as you grow up, your tastes will grow with you. but as Six60 (New Zealand band (I'm from NZ) say, Don't forget your roots.
Even if you take a break from what you listen to now, in a month, or a year, or a decade, you'll go back adn enjoy all the music you like/liked now.
