Idolator - Sparkling and jazzy — and probably the purest pop song on Yours Truly, eschewing the
neo-soul and ’90s R&B influence for a straight-up radio pop vibe, ”Piano” is one of those songs that’s just packed with hooks; even the verses are instant singalong earworms, that clapping beat and kicky piano loop. It’s a movie montage, a summer beach jam, thoroughly current with just enough throwback harmonizing to make it align with the sound of the record as a whole.
