I know this song came out within the last 3 years. It has a very minimal beat, kind of like a stripped down version of sorry by Demi lovato. I could have sworn it was post Malone singing but I’ve been looking thru songs all night and I can’t find it

Glad to be of help OP

demi lovato....post malone solid comp to go off OP

What was the tone? Was it a faster upbeat thing like the Demi chorus or slower like her verses?

The only Post song that comes to mind is Internet due to the extremely minimal beat and some percussion overlaps with Sorry Not Sorry, but you've probably seen that one by now if you've been scrolling through his stuff
