Copy Cat, artist that copy

What do yall think about artist who copy off of other artist style,sound etc?
cause lately i've been noticin alot of artist copyin off of others.Example Christina milian copyin off of beyonce.
Alicia kes copyin off of steve wounder
The girl from plack eye peas tryna be every artist but her self.
I like these artist But i think they really need to stop copyin.
But there are so many more who copy.Thoes are the only ones i can think of from the top of my head.

Whoa...Fergie (Black Eyed Peas) has ALWAYS been unique. From the old Disney show Kids Inc. to Wild Orchid to now. I think she rocks and she is SOOO BEAUTIFUL. I dont see how shes "tryna" be like anyone else other than HERSELF. Ive never seen anyone else with the type of style shes got.

alicia keys doesn't copy off stevie wonder. yea, it's the same style of music with the same genre, and they both play piano, but it seems naive to say that she copied him.

i don't see the chick from BIP copying anybody. True, I wouldn't say she's really trying to do anything remarkably original or inovative, but she still has her own indivduality as an artist. She doesn't really have much opprotunity to be too inovative in the position she's in with the BIPs anyway.
