A comment on our radio today was that whenever he listened to classical music, he settled back in his chair, only to find that it started his brain whizzing round as to whether it was Product A? or Product B? which had used it. So I guess you are not alone!
I reckon I can spot those small bits of records which will be used. My son raises his eyebrows (cos he knows I'm right) whenever I say "this will be sampled for years". It used to be people like The Alan Parsons Set, but is now more likely to be Moby and obviously the Coldplay favourite.
They say that there is no doubt that well-liked music sells products, so they can cash in on people's favourites (and maybe they have a pre-arranged deal with the record company as the record is often re-released shortly afterward?). I guess originality is right out of the window (as we say).
