run devil run would fit with kara.
and i do agree with the person above me, gee would not fit with kara at all.
don't get me wrong, i do like the song but it doesn't fit kara well. it's wayyy too cute for kara.
plus i don't wanna see kara doing the "crab leg" dance..
seriously though, i don't wanna see them doing ANY of SNSD's songs other than run devil run.
the reason is, SNSD's songs are created to fit SNSD, their songs are specific to themselves only.
you can say that their songs have 'SNSD feel' into it.
though run devil run is SNSD song, run devil run wasn't created specifically them.
hell it wasn't even a korean song. they bought off the song. and it's more of a general song.
most groups would be able to pull the song off.
