"Who Knew" is the very appropriate title of pop singer Pink's latest single to climb the charts. You remember Pink; the late nineties ultimate bad-ass pop diva circa "There You Go," "Most Girls," and "You make me Sick," all were chart toppers in there own right. Now, in 2007 Pink is finally getting the much deserved attention her 2006 album "I'm Not Dead" didn't really receive. In fact, the single "Who knew" was released last summer as the follow-up to "Stupid Girls." Now, the single is quickly climbing the Billboard Hot 100 single's chart. In part, Pink can probably contribute her re-entry into pop martyrdom because of Justin Timberlakes world tour this past year. She was his opening act. In addition, the club favorite "U and Ur hand" helped bring some much needed attention to her fourth studio album. I, for one am very excited for Pink, "I'm Not Dead" is a great album. The vocals are arguably the best I have ever heard her deliver. They are so rich and authentic on tracks such as "Who Knew, Nobody Knows, and The one that Got away." Of course, the standout track is the politically poignant "Dear Mr. President." This track could be a model for pop artist making political statements through their music. If you haven't heard "I'm not Dead" go out and get it right now.
