Commercial Breaks & Beats

crunchie_lover is correct, it's "The Polyphonic Spree - Lithium" and it can be found on the "Wait" EP

You can download it on iTunes among other places.

Your dissertation topic sounds very interesting, and it sounds as if you've made a good choice there, although may I suggest re-assessing it to focus on how the music helped sales (instead of placing the emphasis solely on the music itself). I'd also be careful of the way in which you're viewing you...

Does anybody know the name of the 'girl group' that sings the cover version of The Beatles' "Magical Mystery Tour" on the advert?

Never seen this advert, but guessing by the lyrics/description:

Natalie Imbruglia - City

If you recorded it, why not post a sample as an MP3? It makes identification a lot easier

Yes

It's "Sebastien Tellier - La Ritournelle". You can find it on his debut album 'Politics'...
