There's not a whole lot to say about "South Side", the 2nd most awesome irritating song (or the 2nd most irritating awesome song?) of the decade (First prize!).
It's good. I bet you've heard it. I'm sure you've heard it. If you haven't, but like the idea of Gwen Stefani singing very loudly over a slightly annoying and bone-headed Brian Eno-ish song (think Zooropa, maybe?), then clicketh the embedded video forthwith.
If not, might I interest you in some post-punk? JK.
