“I love it when you Get on Down, and Work me babe, On your knees, Once again” !
This implication isn't new, it is current in music like “Down on Me” by Jeremiah and 50 Cent, and Marvin Gaye’s “ Soon I’ll be Loving You Again”, even in the beautiful song “Miracles” by Jefferson Airplane, or "Head" by Prince, and "Down on Me" by Janice Joplin. (I'm getting a collection)
Now that we know what it is about, really what about the music? Everybody just loves this song! This seems to be the favorite song from the album. Apparantly it brings back the older acid jazz style which many associate with the original Jamiroquai feel. But it also has such a smooth sound with the falsetto voice “C’mon Down -c'mon work me baby" in the background.
It begins (and features) an outerspace theme with a strong bass, drums, keyboards (synthesizer?) and maybe even cowbell? (More cowbell!) But the bass keeps the funk going, with the keyboards and trance-like theme. Spacey feel, and sax solo. It is upbeat and is the song that just keeps you going and makes you wanna dance. It’s funky and keeps its groove. Til the end, and then it speeds up almost too fast for dance, and get ready for a landing.
