Your airplay theory is interesting. I do feel like I hear Roxanne on the radio pretty regularly, but then I would also say the same about the rest of the top four.

I feel like I hear it solidly more often than any of the others, and Every Breath also feels far ahead of the other ones. But this is just a feeling. It would be nice to have hard data :)

"Soft Celling" Hah! I had no idea that technical term existed, but it's so appropriately named.

That's because I just made it up.... right now. ;)

If I had been more scientifically rigorous, I would have tracked answers for age, and maybe a couple of other things as well, like familiarity with the band.

I like the cut of your jib. Ah, the scientific enterprise. :D
