Is the world ready for "gangsta accordion" music?

Everybody who's been online probably knows about Gracenote, the giant music database that can fill in song titles and other information when you slap a disc in your CD drive.

But who knew such a thing as "gangsta accordion" music even existed?

Buried in an International Herald Tribune story about Gracenote, you'll find a reference to the bizarre musical hybrid:

Each song is assigned one of 1,600 microgenres, including hick-hop - hip-hop-influenced country - and gangsta accordion, a movement on the south side of Moscow, where about a dozen bands perform gangsta rap with an accordion as the lead instrument.

Google seems stumped -- I'd say this bears further investigation.
