"Dear Mr. President" by P!nk

One of the biggest pop stars of the modern era, P!nk (aka Alecia Moore) puts plenty of her Philly soul into her gritty and boisterous pop. Her chart successes have included four #1 hits so far, and plenty more top 10 hits.

But there is much more to P!nk than partying and scorning ex-lovers. Whether she is empowering others with terrific songs like "F**kin' Perfect", which went to #2 in 2011, or stripping things down to duet with the Indigo Girls to question the President, P!nk is always smart and emotive. The song is from 2006, so the President she was putting on the spot was George W. Bush.
