Norah Jones released her fifth studio album, 'Little Broken Hearts,' this week, and it's already received some of the strongest reviews of her career -- including positive mentions from Entertainment Weekly and the New York Daily News. You can hear what all the fuss is about in this clip from Norah's Wednesday (May 2) appearance on 'The Late Show with David Letterman,' featuring Jones and her band performing the album's leadoff single, 'Happy Pills.'

Jones' solo career has been a journey of slight sonic variations on her multiplatinum debut, 2002's 'Come Away with Me' -- and 'Little Broken Hearts' fits right in, finding her working with producer/Gnarls Barkley member Danger Mouse to surround her trademark smoky vocals with arrangements that boast a little more attitude than usual.

It makes sense given the nature of the material, which Jones says was inspired by a nasty breakup. "I always heard the old stories about how you write better songs when you go through some s---," she told Rolling Stone. "That sucks, but it's true!"

But never fear, longtime Jones fans -- while the new songs may be rooted in resentment, they're still very smooth. Have a listen to this performance of 'Happy Pills' in the clip embedded below and see if you don't agree.
