Meghan Trainor's chart-topping "All About That Bass," has plenty of issues—its muddled message about body positivity and self-acceptance, for starters— but the most common, whingingly pedantic knock on the song is that it's, um, technically *slides glasses up bridge of nose* mostly treble.

Here's the inevitable correction, sung by Avi "Bass Cannon" Kaplan of a cappella fivesome Pentatonix, with backup from Mario Jose and Naomi Samilton.

I hope you're happy, music nerds, and we can finally put this thing to bed.
