[One, Two, Middlesboogie]

I like:

Metal - this is actually a very broad genre... it encompasses traditional Metal, Nu-Metal (which sucks monkeypoo), Death Metal, Thrash Metal, Speed Metal, Black Metal, and elements of Techno, Industrial and Hip-Hop. Death and Black metals are my favourites.
Classical
Rock
early Punk
some Indie - I only like Garbage and Catatonia, and I think Gorillaz are okay. I don't like any other Indie bands... especially Stereo-bloody-phonics.
Dance - another very broad genre. I hate pop-cum-dance, like Shitney Spears and Christina Crapalira. I'm not too keen on Trance, either. Ferry Corsten and the artists in his mixes are good, though... I just don't like mainstream Ibiza trance. I also like Techno, House, Hard House, BigBeat, BreakBeat, Trypno, Hard Hop, Electronica and Techy-Breaky House (okay, I made that last one up). I don't like Nu-Wave, Trip Hop, Garage or Synth.
Reggae
Calypso & Soca - I can't tell the difference between the two, though.
