It was only a matter of time before this happened...
"Bird Flu," suspected to be on M.I.A.'s sophomore album, "Kala," is a certified banger. It's on the Brit/Sri Lanka rapper's Myspace page and, of course, ripped onto a number of blogs, including this one. But it's not been officially released in any way.
That hasn't stopped a remix of the unreleased song — truly an "only in the music blog world" phenomenon. That said, the track uses the chain-gang chant of Kanye West's "Jesus Walks" to do exactly what a remix should: Make the song just as good, just in a different way.
Bonus track: a silky smooth mash-up using T.I.'s 2006 instant classic "What You Know." Takes the song from something you play while cruising in your Land Rover to something you play while lounging on the porch on a hot day.
