here we go...
i have lots of everything, with the exception of C&W (what is the POINT of C&W?), thrash anything, what they call R&B these days (no - R&B is john lee hooker etc.), anything by boy /girl bands, in fact, any music which doesn't move me in some way, whether it's because i can sing to it, play it, feel something or dance to it. music is too important to be mediocre.
i have an awful lot of obscure music, which is difficult to categorise, both classical and more contemporary stuff.
favourites at the mo are mediaeval madrigals (Oxford Camerata, Pro Musica Antiqua); the chemical brothers (BIG beats); tambours du bronx (an insane french industrial percussion group); cocteau twins; "pixie psychedaelia" (my friend's group, jabberwocky); arvo part's summa; debussy's estampes; badmarsh and shri (a fusion group, mixing asian tabla with drum and bass); steve reich's marimbas...
erm...i think i should stop, now.
