music on adverts

Sometimes the people choosing music get it spot on. You find the whole tune on the internet, and that short section used is the only decent bit of the whole song. You wonder, how the hell did they find that amazing bit amongst this crap. I'm speaking of "Release Me" by Oh Laura (some car advert I think--sounds a bit like Regina Spektor) and "Away From Here" by The Enemy, currently used on the ER advert. So disappointing.
