For a guy who made his name driving party people to ecstasy, Moby has always had a thing for the blues. His unlikely 1999 megahit, Play, used them literally, grafting ancient samples into inviting electronic grooves. His latest uses them spiritually, giving his melancholy streak room to brood and blossom. Instrumentals like "Shot in the Back of the Head" (Google the haunting video, directed by David Lynch) billow moodily, lush arrangements glowing with Eno-style analog-synth warmth. Never the most convincing singer, Moby wisely farms out vocal duties to friends — all of them unknowns and ripe for discovery. It's a return to form but with a wider romantic streak. Age will do that.

“Satisfied”

Only the genius of Tom Waits could combine the subject of mortality, a reoccurring theme in his work, with wordplay that name checks both Mick and Keith, whom he calls "Mr. Jagger" and "Mr. Richards," and the title of their magnum opus, "Satisfaction." And to show just how cool Waits really is, he even got Mr. Richards to play along, one of nine guest appearances the guitarist has made on three Waits albums. "This growling roadhouse stomp is a late-breaking response to the Stones' greatest hit," Rolling Stone said of the track.
