Too lazy to go through and quote, but...
Thanks to the OP for the link to the South African bands. I'm digging that stuff - reminds me of Dispatch

I like the music for Diablo Swing Orchestra, but not so fond of the creepy vocals...
Likin' the Basics.
Used to have a Warren Zevon song about hockey, but I lost it somewhere...
I have a Kevin Devine song which is awesome.
Obscure-ish stuff I like... (I don't watch any music TV or listen to the radio at all anymore, so I don't really know what's out there, but here's a list of stuff I don't think too many people know about...)
Popium - A Norwegian pop group - heard them on a Korean drama of all places, although the drama was pretty popular, so some people may have heard of them.
Roger Cicero - German Jazz/swing music. Way better than Michael Bublé. Probably not obscure at all in Europe.
Thomas Fersen - French chanson. Not sure how to categorize it in American - pop with some jazz influence? I thought he was somewhat popular in France, but I met a French girl in Germany and she said she hadn't heard of him.
Criscoh - Slow, sad, drifty. Also check out his art, it's even better than the music.
Philip Zeplin - Another artist with a music hobby. Alt-pop.
Starlight Drifters - Rockabilly!

There would be more, but if it's too obscure, I probably wouldn't be able to find it, and therefore wouldn't remember it...
