It has nothing to do with the leg-spread. This is just for eye-candy.
SNSD has never been an album-driven group. I'd know since I own a few of their albums. After their debut album, things went downhill in the non-title track departure right up until they had their least-favoured song, "I Got a Boy," where all the other songs on that album (minus those two ballads) were pretty good. However, after all of the hate this album has been getting, I feel the need to stick up for it since it is one SNSD's much better albums.
