Jewelry is good too but sort of old.
I was thinking more of new-age girl groups.
But ET dance is cute ^^.

WG ftw

honestly.. both groups cant sing that well.. but.. if i had to choose..

WONDER GIRLS!

TELL ME TELL ME TE TE TE TE TE TE TELL ME !

Its not "Tell Me" anymore.
Its "SO HOT"

Vocal wise 소녀시대 good songs and better skills in singing (PRETTIER!!)
But 원더걸즈 = more addictive songs and good marketings (CUTE)

SNSD by far.
