A new group on my radar

Yesterday I was watching the Today Show (while feeding Zoe, our morning ritual) and caught a segment on a group I never heard of but who apparently won a grammy. They’re called Ozomatli and they sing a lot in English, some in Spanglish, and some in Spanish. I found this song on YouTube:
La Gallina
The fact that Universal labels it “clean version” gives me some pause, but I read the lyrics and watched the video and didn’t see any reason for concern. I don’t really understand it–is la gallina his girlfriend and someone’s taken her and he wants her back? So I’m probably missing something–see what you think and let me know.
