Before this song, I was not a fan of these ladies. I found them to be your standard R&B girl group, albeit with pretty solid harmonies.
After this song, I saw they were something more - edgier, not afraid to break out a guitar, almost bombastic in their harmonies. Even the songs I thought were standard R&B fare sounded just a little bit more solid to me, now that I was looking back on them with a different perspective.
As it is, this song hails back to the funkmeister himself, George Clinton, who famously said "Free your mind, and your ass will follow." This is slightly more family friendly, but still carries the same sentiment. Plus, it rocks.
