Wednesdays are so...meh. The weekend beckons, but wimpily, and the sunshine taunts from outside our windows. To bust your (and our own) hump-day slumps, we've compiled an endorphin-rousting, good cheer-inducing playlist. Feel free to add on. If you want to listen, most of the playlist (except the filched limewire ones, bastards!) is on itunes, under GuestofaGuest Playlist.
