Ahahahahaha! I agree with the fist three, but a Cm7 doesnt sound like getting rejected, it's more like your little puppy dying. I'd say rejection sounds a lot more like somebody smashing their fist down on a piano, which would be a Cm7 flatted 5th, added 9th, a copule of more random notes here and there, and definitly a sharped 13th. (Hmmm, actually I think it'd have to be flatted 13th.) Anyway, it's kinda dissonant if ya'd ask me. Then again, I guess trumpet players might express their anger in a different way.
