Track is lead single from forthcoming greatest-hits album of same name

It’s her final release on Warner Bros. Records and isn’t due in stores until next month, but the party got started a little early when Madonna’s latest single “Celebration” leaked online last night.

The title track from the Material Girl’s greatest-hits compilation leaked to file-sharing sites across the Net and it’s AMAZING. “Celebration” is a hot, hip and fun dance track that goes back to Madonna’s early heydays with albums loaded with music you could shake your booty to. The pumping house beat is so intense, you can’t help but get up and dance.

The track was produced by legendary DJ Paul Oakenfold and is one of two new songs on the album, which is due in stores September 29. The song is scheduled to hit radio on August 3. According to a Warner Bros. press release, a video for the song was recently shot in Milan and was directed by longtime collaborator Jonas Akerlund, who helmed her “Ray of Light” clip as well as working on the documentary “I’m Going to Tell You a Secret,” which followed Madonna on her 2004 Re-Invention Tour, and a television special on her 2006 Confessions Tour. The second song on Celebration is reportedly a collaboration with Lil Wayne called “Revolver,” a Weezy-less demo version of which has been making the rounds on YouTube since May.

Celebration will include hits from Madonna’s entire Warner Bros. career — in 2007, she left the label to sign a lucrative, all-encompassing deal with concert titan Live Nation — and although a full tracklist is yet to be announced, Warner’s press release mentions songs like “Everybody,” “Express Yourself,” and “Vogue” as making the cut.The album will be released in a variety of formats, including a single disc, a deluxe two-CD set, and as a DVD, which will feature some of Madonna’s best-known videos, including some never before available on DVD.

Celebration” will also be accompanied by a music video, which features Madonna’s daughter Lourdes. This is the first time Madonna has featured any of her children in her work and since Lourdes has morphed into a teen fashionista, it will be fabulous to see her on screen. The video for “Celebration” will be released at the end of August.

Madonna: Celebration – The Definitive Greatest Hits Collection, arrives September 29.
