Well, fuck me. Who Knew is most definitely her best song for me. It kinda starts out as a lovely little mid-tempo, but then that chorus sets in and it only builds from then on. The way P!nk lets her vulnerability show, especially in that middle 8, without losing power is something only she's capable of and which is why I was such a stan back in the day. It's not the winner here, but it's my winner.
