Honestly, you never know what will happen. Royals didn't sound very radio-friendly either and that was a #1 hit for Lorde.
And Take Me To Church went #2 right?
Yes Girl could do well if it's promoted. It's certainly a lot more radio-friendly than Stone Cold
Royals was radio friendly and catchy af once you heard it for the first time it had that feeling like damn this could be massive. This is great and really mature I love it and hope it'll somehow take off but yeah it's not radio friendly but you never know.
