Not sure if this is relevant here.

My tolerance for people faking a US accent when they sing has declined over the years, so a while back I started making a Spotify playlist with tracks where the (usually native English-speaker) vocalist sings in English with their real accent instead of a fake US one. And I called it “No Yankcent”.

Maybe people have some tracks they can suggest.
