Does Anyone Else Listen To Mostly Sad Music?
For me, it's either it's sad, somber, melancholic, in a minor chord.. I can't think of too many happy songs I have in over 5,000 mp3s.
Sometimes singles (Billy Joel's "Pressure" as an example) are released in a major key as opposed to the album version in a minor key.
I also like dark stuff, and not necessarily diminished chords. Those Sabbath riffs, again, usually reverting to a half-step instead of the whole-step, Middle-Eastern vibe, ala The Doors and Pink Floyd.
I know David Gilmour said it's very hard to write a happy song. I love his "sad" guitar solos.
