Passion Pit. Okay, maybe not exactly 'No One', but..http://gossamer.passionpitmusic.com/
Loud, bright electronica (pop?), with influences of pop, some R&B, and catchy tunes.
And if it's not your thing, do not let the cheery tunes and saccharine beats lull you; all of them has plenty of depth, plenty of.. this ... repressed quality. Almost like something that will explode.
Which would be awful for the artist, but for the music? Brilliant.
I'd maybe try to listen to all of the links here someday.
