The hip-hop laced album has 12 tracks, including collaborations with Timbaland, Justin Timberlake and Pharrell Williams. The album-closer, for example, "Voices," features production by Timberlake, Timbaland and Nate "Danjahandz" Hills. The song builds to a dark, cinematic crescendo, as the album ends with one lone tone.
Kanye West also offers a fast-paced rap on "Beat Goes On," the eighth track, breathlessly rapping, "I think I'm going to try something new."
Madonna's decision to release her eleventh studio album for Warner Bros. Records on MySpace before it lands in stores, follows similar moves by Nine Inch Nails, Black Eyed Peas, Outkast and 50 Cent, who also premiered their albums on MySpace.
