oh.... ok... so now that woody opened up that can of worms.. lets see... I will post the oddest list of them all (order has no meaning here)
1. classical (organ music : I head tocatta in couple cathedrals around Europe... the sound and feeling is not to be forgotten!!)
2. ballads (primarily guitar, a lot politically driven, mostly Visotstki, Okudzawa, Sojka and Kaczmarski. SOme of you might have heard of first two, I doubt if you heard of the latter ones.
3. Classic Rock (I will classify into this bands like Led Zep, Pink Floyd, Queen, George THuroughood and the Destroyers, The Doors, JImi Hendrix and such)
4. Hard Rock (music of the ACDC flavour)
5. Metal (metallica, apocalyptica, Megadeath and many others)
6. Punk Rock
7. Scottish Bag pipes (old tunes)
8. Sea Chants (something like the drunke sailor but more rythmical, primarily sung in the olden days on tall ships)
9. Bluegrass
10. rags (Scott Joplin and such)
11. whole sorts of blues, although I Think I'm most partial to Delta Blues

12. Jazz (oh... Louis Armstrong... Ella Fizgerald now that's good stuff... have you heard the one "baby it's called outside" ?)
13. Big band music from the 20's

14. Old Country (have you seen rio bravo? that type of country)
15. Some Folk (have you ever heard "alice's restaurant" ?)
and many many many more as I know that this list seems too short...
I burn audio CD's every so often and when people borrow when them they return them they look at me like I'm nuts due to the wild combinations of stuff that's found there

P.S. I had rap (I actually don't consider it music) and some of the weird stuff from 70's /80's that's called Disco... I think it's called that cause it had to be discontinued to save the humanity from the pain and suffering it caused LOL
