I checked it out as well...that is very simple and catchy, and with no vocalline, it tends to make me want to "ADD" it.
I have written many many vocal lines for people who dump instrumental jams in my lap, and this one is an "easy" target for a nice melodyline for vocals...ALSO I know it's a rough-cut, but at the break around 3 minutes, I would have gone nutz on the bass as a cool soloing area...
