So here's the great pop album everybody was hoping Adam Lambert would make, ever since he ran wild on American Idol three years ago. It wasn't just Glambert's dynamite-with-a-laser-beam voice that got him into our national knickers: It was his warmth, his humor, his burlesque bravado. His 2010 debut, For Your Entertainment, was a typical Idol quickie – decent, but it needed more personality. Trespassing delivers, with a mix of tinsel disco-club sleaze and leather-boy love ballads. While he excels in a radio cheddar bomb like "Naked Love," he gets deeper in slow jams like "Underneath" and "Outlaws of Love." But all over Trespassing, Glambert sings everything like Zeus in a thong.

“Help Me”

Joni Mitchell wrote and recorded this song for her album Court and Spark, but she had to switch from her regular band to make the song sound exactly the way she wanted. "I had attempted to play my music with rock & roll players," she told Rolling Stone. "They’d laugh, 'Awww, isn't that cute? She's trying to teach us how to play.'" Mitchell switched to a jazz band, Tom Scott’s L.A. Express, and scored the biggest hit of her career in the process.
