here's a question for you. you hear a piece of music on the radio and you think nothing of it. yet it's on an advert and everybody loves it, can't live without owning it and goes to great lengths to find out what it is. WHY? Nobody could possibly have such catholic tastes in music as to REALLY like all the tracks mentioned above (enough to buy them), surely? There's so much good music out there that DOESN'T appear on adverts - go seek it out. Start with the new Coldplay album. Rant over. NB this is not a personal attack on the asker of this question - i'm just curious why people behave like they do.
