The Song:

Shirley Manson is famous as the lead singer of the band, Garbage. It was reported here that she collaborated with Beck on a song for her upcoming solo album. Beck's right-hand man, Justin Meldal-Johnsen, is also apparently working with her (he's worked with Garbage in the past too). More info still needed, and will likely come soon.

UPDATE: This was a false media rumor and is not happening.
