"Unoriginal" isn't necessarily a bad thing when everything else is so pleasant to the ear. I love her voice and this song is soothing and beautiful. There really is no need to be original here in my opinion.
This was the reason I wasn't a fan of this album in the first place. It really put me off. It's not a bad song, it's just really verging on unoriginal, boring, poppy shite (in comparison to their original, fun Goldpop).
