It's peculiar how intolerant some people are of others' interests. If people are interested in knowing details of advertisements' tunes or personnel, then fair enough. that's their "thing" - if you don't share that interest then just ignore it, don't knock it. It's no different from say, train spotting, or for that matter posting in ChatterBank. Each to their own, the cosmopolitanism makes for a more interesting world. How boring it would be if we all had just one overpowering interest (e.g.Stamp Collecting) to the exclusion of every other potentially exciting hobby.
P.S. I think the Red Cross ad is a cut above the average ad.
