their salary may not be bigger than Nicole ..but still, they can sing (atleast) ..they should have like, solos ..if they were like Danity Kane it'll be much better

i don't even understand why do only Nicole has to sing

i dont think the other dolls even thought of becoming this famous when they were turned into a recording group. the others are just dancers who can sing a bit. so they should be thankful that theyre even this famous and gets to travel around the world just to do their passion which is dancing.
as for melody, she sings in the chorus of most of their live performances, she back up nicole's vocals.

the 'back-up' recording track of the actual song is so not needed. the other dolls can do it... but ..
nooo. they must put up the Nicole back-up track.

i love PCD and Nicole . but its just.. getting too much.

that was amazing ... . god this girl can SING, and I love PCD for actually always singing live. THAT's true talent!!

i do think it was overdone to have the dancing in the background.
