Who Knew + Since U Been Gone = BFF

I admit, I like this song in almost exactly the same way I liked this song. Wholeheartedly and on repeat at the gym and even those times I hear them and they (inexplicably) make my eyes tear-up a bit. I know nothing about music but I think they might share something in their structure too.

Hit "play" on both of those at the same time. The videos even have a similar number of seconds of "just doing stuff to set the scene before my song starts" noise before they begin. Both have the same type of build-up of the verses and then crescendo-ing choruses, they both repeat a phrase a few times at the end of each song. They are the same song. And so, I do not feel as bad that I'm so taken with both.
