Madonna-Justin Timberlake collaboration leaked (Yahoo! Music)

Said to be called "Candy Shop," the song appeared on putfile.com, but was removed following copyright issues. The track is a mix of dance, pop, and hip-hop and will appear on Madonna's forthcoming album, scheduled to be released in November.

"Candy Shop" is just one of several tracks she worked on with Timberlake and uber-producer Timbaland, both of whom have been writing and producing songs as well as adding vocals. Pharrell Williams and Mika have also been involved in the album.
