I never ever listen to pop-music, but every summer I used to drive my parents car for 1-2 weeks. So I always got a fresh set of songs every summer, and every year there were between 0 and 2 songs that I found genuinely good (and I knew little or nothing about the artists). The last time was in 2011 (I think) and Rolling in the deep was the only song I liked. I'll go back and look through the producers, would be cool if one turned out to be Max Martin, but I somehow doubt it.
