Meghan Trainor dropped her new song 'NO' today, and it's so good we insist you listen to it right this minute.

It's the girl power anthem that we had no idea was missing from our lives until now, and with a chorus that just won't quit Meg's got a hit bigger than 'All About That Bass' on her hands.

Our fave lyrics go a little like this: "My name is no/ My sign is no/ My number is no/ You need to let it go."

SASS LEVEL: 1000.

Chatting about the track, the Grammy award winning singer told EW: "[My label boss] L.A. Reid told me I didn’t have a single."

Adding: "He said I have an album of Nice Meghan and that I needed to be sassy. So I said, ‘I’m going to the studio to write you a smash!’

"I told my producer [Ricky Reed] we needed a big eff-you song, an anthem about girl power that sounded like nothing on the album. We wrote it that day."

No joke we've listened to it 13 times already.
