I've just listened to a LQ audio of Clumsy and I'm not entirely sure what to make of it yet. I think a lot of the more intricate details of the production are lost because of the quality. It's a bop, that's for sure. To me, this is being played at a party that looks like a cross between The Fifth Element and The Great Gatsby.
It's also clear that Britney's voice has been given room to really shine with the album because again with this track, her lower voice is a real highlight. I don't know how to explain it but there are flourishes in the outro where a sample of her falsetto is used. To me it's angelic / otherworldly, like a Siren call off in the distance. I can't wait to hear the HQ version!
