eeeeeeeeeeeew none of them tbh. Hot N Cold and Poker Face snatched both easily

maybe because you are a gaga fan

Just Dance.

That's why it sounds so bad now.

Just Dance has aged terribly, I Kissed a Girl could be released tomorrow and easily be just as big as it was in 2008.

I love both, but I will go with ikag

No but try again.
I'm a fan of BOTH of them.
JD is just the better, more iconic song

All of this.

Just smash, gonna be ok
da duduuu
Just smash, smash these records babe, dadadudu

Love both tho '-'

Just dance was one of the few songs that revolutionized POP Music, IKAG is simply not from these songs.
The truth is that JD was more experimental back then while IKAG with all the lesbian thing was safer.

And although I agree about JD being dated, IKAG is also dated.. I mean both sound really dated.

Bad Romance can be released now and smash, the same goes for Poker Face, but definitely not songs like Just Dance/Hot N Cold/IKAG/LoveGame
