M!ssundaztood, originally issued in November 2001, firmly established P!nk as a major post-modern pop-rock artist around the world. "Get the Party Started" became a chart-topping anthem for the ages, and hits like "Don't Let Me Get Me" and "Just Like a Pill" rocketed up the Top 10 of the Hot 100, while the aching R&B heat of "Family Portrait" went Top 20. Having sold well over 15 million copies, the album - which also boasts guest appearances by Steven Tyler, Linda Perry and Scratch - stands as P!nk's most commercially successful release to-date.
