Ride a Space Cowboy.
(You don’t usually see country western anime music videos. But this Cowboy Bebop mix is very nice.)
And another one, this time not C/W, but with a fun song called “Stress,” by Jim Infantino/Jim’s Big Ego. (Other stuff by JBE I’ve found is also good. Hey, they even link to their ripoffs remixes. How awesome is that?)
