I'm not even going to try to stick the correct "genre" labels on my tastes...
German music: Accept, Scorpions, Dorothee Pesh, Rammstein.
UK music: Beatles, Iron Maiden, The Who, Led Zeppelin, Queen, Black Sabbath, Sisters of Mercy, The Cult, Portishead, Deep Purple, old Fleetwood Mac, Mike Oldfield.
US music: Madonna, Kiss, WASP, Rolling Stones, Jimi Hendrix, The Doors, new Fleetwood Mac.
Misc others: Loreena McKennitt, Clannad, Gregorian music, Cruachan, Brahms, The Russian Red Army Choir, Vaya Con Dios.
And probably 50 more that I can't be bothered to try to categorise. The UK bands do seem to take up a disproportinate space in my CD collection
