I love the song. Very retro & funky.
I could understand people complaining about the line-distribution if it was a recent development.
But the truth of the matter is it's been like this for many, many years now. Seems a bit late to harp about it now.
It's one of the things you know going into it.
Plus about 50% of the song is the girls singing in unison (a fact that many are apparently completely disregarding), which means guaranteed PV time so I really don't see the problem.
In any case, can't wait to hear the coupling songs, because this single is an allround win in my book so far.
