Commercial Breaks and Beats :: The UK TV Advert Music Database

"Commercial Breaks and Beats aims to provide you with the Internet's most definitive directory of UK TV advert soundtracks."

A song that I like has popped up twice in unrelated events (once in iTunes and once in a TV show) today, and my girlfriend was surprised that I hadn't heard it on TV before. She said it was from a film or an advert, but couldn't remember where she'd heard it. IMDB brought nothing relevant, but a quick Google found this little gem. And the answer: Apple's iPod Shuffle advertisement. I should've guessed.
