Pretty much, my collection branches in just a few directions. Those branches cross typical genre lines though. I like female vocalists. This means Poe, Sarah McClachlan, Maire Brennan, Martina McBride, and Kittie. I like ambient. That means Enya, Enigma, Dead Can Dance, Holst (as in, Holst: The Planets), and anything trance. I also like big thunderous drum and bass metal. Metallica, Disturbed, Kittie again, Slipknot, Queensryche, and ummmm... I can't believe I forgot their name... DreamTheater. I also like Irish/Celtic music, which tends to cross over with the female vocalist and ambient sections. Clannad, Enya, Michael Weylan, others whose names I do not know since they come from compilations CDs.
Then there are the rather unclassifiable parts. Bad Religion, Depeche Mode, Sting (for crying out loud). Some of them I will depend proudly, others... well, I just won't admit to them, okay?
