I would say that I like the following genres:
Pop
French-pop (if that's a genre)
pop-rock
soft-rock
rock
progressive rock
Progressive fandango-rock (if that's a genre. It's the only thing I think fits Carmen's "Fandangos in space")
psychedelic rock
psychedelic pop
acid rock
Power rock (Grand Funk, etc.)
jazz-rock (like Billy Cobham, etc.)
Hippie crap/singer-songwriter stuff
folk (like Donovan, etc.)
Folk music (whether it's scandinavian, rumanian, greek, african, etc.)
Classical (I can't really tell the different genres apart, but I have records by Beethoven, Mozart, Bach, Rachmaninov, etc.)
Opera (Bizet's "Carmen" is the only one that comes to mind though, unless Mozart's "Requiem" is an opera)
jazz (mostly traditional, but also a few things in the more experimental area. A lot of this psychedelic/free/avantgarde/fusion jazz is some of the worst crap I've EVER heard (Miles Davis' "Bitches brew" being one of the worst records I've ever had in my collection!), but stuff like Teddy Wilson's "'Round midnight" and Oscar Peterson's "Wheatland" are among the best songs I have EVER heard!)
Vocal jazz (like Toni Harper, Billie Holliday, etc.)
Jazz-funk
Funk
Soul
Disco
Film music
A couple of musical songs (Gershwin's "Summertime" from "Porgy & Bess" being my alltime favorite track)
Country (well, not much, but I have a couple of records by Billy Strange, Bobby Bare, Johnny Cash, Merle Haggard, etc. and Lee Hazlewood, which is more country-pop is my favorite artist)
And then I'd also have to say country-pop now I already mentioned Lee
Heavy metal
Black metal
Doom metal
Gothic metal
Hardcore (Biohazard, Sick of it All, where Biohazard is the only one I have)
Progressive metal (Dream Theater, and maybe Opeth counts)
Power groove (Pantera)
A few death metal songs
Grind (a couple of Deicide songs is the only thing, I guess)
80's metal (GN'R, Skid Row, etc. (lots of horrible crap in this genre)
Psychobilly (Nekromantix and Condemned are the only two I have in this genre, I guess)
Thrash (Machine Head's "Burn my eyes" & a Forbidden record are the only ones I have)
Stuff like Empyrium's two latest and Ulver's "Kveldsanger"
Kraftwerk
Frank Zappa
Stuff like Dead Can Dance, Clannad, etc. I don't know if that falls into spiritual or something (Clannad probably more folk-music).
Punk (A Dead Kennedys record is the only one I have, if Hellacopters don't count)
Glam rock (only a few records)
Blues (only a few records)
I guess some old Rn'B (Rhythm n' blues), not the Rn'b today, but the stuff from the 60's.
Hard rock (Rainbow, Deep Purple, Aerosmith, Audioslave, etc.)
World (Ismael Lö, Bau, Cesaria Evora, etc.)
Grunge (Soundgarden, Boghandle & Pearl Jam's "Indifference" is probably the only)
Stoner rock (Queens of the stone age)
Reggae
Dub (I don't think I have any dub, but I like some of Aswad's songs)
Instrumental stuff like The Ventures. I don't know if that kind of categorizes as surf, but I'll have to mention...
Surf now, as I have a cd by Dick Dale
A few 80's hits (Level 42's "Running in the family", Dead or Alive's "You spin me round", King's "Love and pride", etc.)
Latin (I don't really know the difference between such genres as mambo, cha-cha, bolero, etc., so I just label all of it "latin". I have records by Ray Barretto, Perez Prado, Xavier Cugat, etc.)
I don't know if that's it. Maybe there's more. I usually say that I listen to any kind of music that existed before the 80's, except gregorian chants and some other genre that I can't remember now (but it starts with a p, as there used to be to p's - the other being punk).
Most of my record collection is from the 60's & 70's. There's not much besides metal, world, film music & a few things here & there I like that's newer than the 70's. I used to listen to hip hop, house, trip hop and stuff like that, but I grew tired of it. There was a lot of records in that area that I bought, listened to 5-10 times and then never listened to them again and there were fortunatly also songs I listened to 5-10 times on mtv/radio, got tired of them and therefor didn't buy them. When I say "get tired" I don't mean that I think it sucks now. I don't think there's ever been a record/song, since I started to get interested in music in the late 80's, that I listened to at home and really liked that I now think sucks! The stuff I listened to earlier and got tired is now mediocre to me (but not crap and not good).
The thing is though, that I have gotten really tired of that electronic sound that everything has nowadays. To me it sounds super corny and gross if you can hear that it's just a button on a computer that has been pushed instead of real instruments. A lot of times it sounds like it has deliberatly been given a synthetic sound - a sound that can't really be produced by an instrument - and that's even worse for me. An example is when I saw "Requiem for a dream" and I heard the the strings on the theme. I thought to myself "Mayn, that's some bad-ass strings [nothing beats strings if you ask me]! I'll buy that soundtrack" and then the worlds grossest crap-drums comes on and ruins it all completely!!!!!! Why not just leave it without drums or at least use some real, more subtle drums, like John Barry does on "Fred & Cyd" for instance?
Well, enough rambling. I don't really like dance and other electronic genres, although I can guess I can find okay stuff in all of it (but okay is not good enough to listen to IMO). Drum n' bass is probably the worst genre I know! I can find okay stuff in that as well, but stuff like Bad Company (complete with rip-off name) has made some of the worst crap I've heard my entire life!!!!! And I know about drum n' bass, as one of my best friends is a drum n' bass maniac, so I've probably heard several hundred drum n' bass songs.
