Reading.
Listening (to music and intelligent conversations.... and sometimes complete bollocks).
Writing (music).
Playing the guitar/computer.
Being with my friends.
Like-minded people.
I have a list somewhere, but I keep having to update it. It's quite long.
Mostly metal. Nearly all of it. Death, Melodic, Heavy, Prog, Black, Battle, Pirate, Grunge, Doom, Nu-, Power, Hair, Melodic Death (In Flames are my favourite band)... I think you get the idea.
I really enjoy older/classic rock, folk, acoustic and classical music amongst other styles.
I also find Electronica strangely pleasing! Although I don't listen to it out of choice.
Most mainstream music I won't bother with. It's either dull, or rap. I don't find rap very poetic I'm afraid.
Rimsky Korsakov, fuck yes!
Films can be good.
Heroes
Doctor Who
Stargate SG-1
