This is a tough one. Not because I listen to a lot of stuff, but because I have so much stuff I like. I can report with authority that it is possible to blow those entry level Creative Labs stereo speakers and your sound card by playing Bach's Tocatta & Fugue at unreasonable volumes. Ever had a metal head complain your music was too loud?
Mudhoney, Smashing Pumpkins, Beethoven, Bach, Schubert, Crosby Stills & Nash, Sweetwater, Led Zepplin, Rammstein, ZZ Top, Brahms, Tchaikovsky [Can never spell that name right]..
But normally I find myself listening to odd things such as Dr. Demento, Weird Al Yankovich, Music to Shave Hamsters By [German Techno compiliation], Trance, and Ibeza.
Of course, with how extensive my music collection is, I rarely hear the same song twice in two months [Huge playlist].
Harm none,
