eh i never bother to read the comments. their voices in that version arent as good as when they covered it on triple j. but i definitely wouldnt say lorde saved the song because she isnt that strong vocally if haim were bad she definitely didnt kill it.
but on the topic of haims voices being weak, they definitely arent the most talented vocally but growing up, they obviously werent as vocally trained as pop singers would be but im fine with that. their voices work really well in some sort of way, especially because their so passionate while singing its incredible and idk it just works for me
