Okay, I honestly accept your judgement for being a Post Malone fan, but I think we can at least agree that his song 'Better Now' would be absolutely amazing as an 80's power ballad. This YouTube cover is proof.
I feel like people have a love/hate relationship with Post. By that I mean you either love the dude or can't stand him, but c'mon - this is way too catchy to hate on. And yeah, I realize I'm advocating for a rendition of the song that's not even performed by him.
I'm just saying - Post Malone, maybe get yourself into the 80's power-ballad game. That's all.
