Hmm..I mostly listen to a wide range of Metal bands but like you I listen to everything. I saw some familiar names in your list: Coldplay, A7x, Metallica, Celtic Woman...really, I variety of music you have there.
I'm alittle more...random? I never know what I'm gonna listen to next. One moment I can be emotionally moved by Celtic Woman's music and the next find myself headbanging to All Shall Perish...but I have noticed that I listen to more Melodeath and Electro/industrial during the night hours and listen to 'lighter' music during the light hours...I dunno what that means
