As for who else, I think that recent New Yorker article mentioned that when Springsteen wrote "Dancing in the Dark" he didn't want to include it on Born in the USA because it was too poppy. Or something along those lines.
"We Belong Together" is an interesting case, because the song takes one hooky 4-chord progression and manages to create three distinct song sections out of it by varying the melody, pulling drums in and out, and changing the chord voicings--but it's still just the 4 chords, all the way through.
From a songwriting perspective, it's a pretty nifty trick, but the danger is in too much simplicity. A whole album like that would be pretty banal stuff. But for the one song, it's a catchy progression, and they milked the hell out of it.
