I listened to your problems, now listen to mine.
ah ha! i heard "heartbeats" a couple of years ago, then quickly forgot the artist and title of it and pretty much resigned myself to the fact that I would just have to wait until someone else mentioned it again since I really had nothing else in my head other than, "latino-ish named acoustic singer, singing a cover or someone else's song." This time I wrote it down; do you prefer the version you linked to Gonzales's?
The Knife writes good songs. Itunes and Pandora think The Knife should be my favorite band. I think there arrangements are rather terrible. Somebody covering their music solves this problem. I like this more than the original. Also I need to figure out why the interwebs insist that I like The Knife.
