iTunes Single of the Week: Duffy, "Mercy"

This week's free single, "Mercy," comes from British newcomer, Duffy.

The song definitely similar to Amy Winehouse. It's a mix of old school R&B and sharp pop melodies. "Mercy" lacks the edge of Winehouse, but that's what makes her unique. Duffy's voice is higher and the vocals have more diction.

One of the song's hooks is the upright bass riff that is repetitive yet not annoying. The groove of the song is steady and the electric piano supplies another hook. Add the catchy chorus melody and you've got a song full of hooks.

This song proves once again that the Brits are producing far superior pop music than anyone in the U.S.

Duffy's debut album, Rockferry, will be out in the U.S. on May 13.
