Are you listening on laptop speakers or something? The production on this track is bedroom producer garbage tier which is a testament to how good the actual composition is. I mean, the song objectively sucks with the sloppy cut-and-pastes, her terrible breathing technique, harsh transients on the kick, shotgun, and vocal plosives, squashed EQ via some awful software compressor, etc. It’s inarguably a low-quality production. There’s a reason why good producers slave for hours fixing those issues, and despite all of the flaws there’s still enough there to hook you. I’m not saying my pick should have placed higher; I’m saying I don’t think you’re hearing everything in this song if you think it’s the nuts.
M.I.A. said that she recorded her vocals without paying much attention to her singing and finished the song in one take.
And it shows.
