Though I used to subconciously listen to metal and not really like it, all the music my brother used to play when I was a kid is now my favourite! When I was younger I was into dance & chart music and some rock, bands like Queen, Phil Collins, Genesis, Michael Jackson... I still like all that but now I love metal much much more :p
Bands like;
Metallica, Pantera, Sepeltura, Lamb of God, Soulfly, Nirvana etc
And other artists I enjoy listening to are:
Lenny Cravitz, Hendrix, Bob Marley, Primus, some Eminem, Nicky Blackmarket etc
And lastly classical music, film score composers etc.
