Amazon.comAdam Sandler plays an immature 32-year-old who adopts a son to prove to the girlfriend who just dumped him that he can be responsible. Those familiar with Sandler's Saturday Night Live shenanigans won't be surprised by his behavior, and several of the movie's bits are interspersed throughout the soundtrack. For the music, it's a mix of straightforward rock (Garbage with "When I Grow Up," which sounds suspiciously like Vanity Fair's "Hitchin' a Ride"), unexpected covers (Sheryl Crow refining Guns N' Roses' "Sweet Child o' Mine," Everlast and the White Folx tripping out on Neil Young's "Only Love Can Break Your Heart"), '70s kitsch (Styx's "Babe" and Yvonne Elliman's disco anthem "If I Can't Have You"), and inquisitive singer-songwriters (Rufus Wainwright, Shawn Mullins, who asks the George Harrison question "What Is Life?"). Melanie C (Scary Spice) surprises with the rock-oriented "Ga Ga." Just in case things seem too serious, Tim Herlihy ends things with the Mr. Rogers-like "The Kangaroo Song." --Rob O'Connor
