hmmm... you're music tastes are kinna different from mine!
I guess I could point out some stuff that you'd never thought of listening to though!
you may enjoy the soundtrack to Everything Is Illuminated- it has quite a few bands that I'm quite fond of on it!
You may like Leningrad (can't type in in the cyrillic alphabet here
)
The Gypsy Kings
Gogol Bordello
Seu Jorge
Manu Chao
And being deeply in love with Irish music I wouldn't be myself if not advocating
The Pogues
The Dubliners
Stiff Little Fingers
Flogging Molly
Dropkick Murphys (American Boston Irish)
ummm... yeah... I guess I'll stop there!
