Whenever I'm in a bad mood or had an awful raid night, I always turn to swing and big band. I don't know why, but it just turns my mood around.
I don't listen to music too much (I'm more of a movie buff), but I've been in the same situation that you're describing lately: I'm just sick of everything I usually listen to. I've decided to poke into my archives a bit for some old (real) jazz, blues, and even classical, which seems to be a great change of pace. Stray a bit from your normal genre preferences and you might find something new that you like.
Oh, and Seerah, most of your list of favourites is eerily similar to mine
