The site songtitle.info has been/is building a huge archive of all the songs they’ve used in commercials. Some of the listings go back to around 1996! Although it mainly focuses on North American broadcasts, a lot of those clips feature the same track when aired in Europe and most likely in other parts of the world as well. Nice initiative, and very amusing. I think they have a pretty good deal with Amazon because all of the album links go there for the sample image. There doesn’t seem to be audio files available, which kind of makes sense with the DMCA stuff and all those thingies.
Who would have thought that Dell (for the XPS Laptop) and Dentyne (for Tango) would both have used the same Squeeze song (Tempted) to promote their products. Funny.
Anyways if you’re ever stuck with a ‘damn what’s that song’ question: check out songtitle.info
