Okay, this was really tough but I just think that Rebecca Black has no talent at all [or at least she pretends that]. I don't like Justin Bieber either but I don't know...he's a bit better than her when it goes with talent otherwise he is just as annoying as Rebecca.

Their songs are both horribly written, but at least he has a decent singing voice...

No clue. D: Never heard of Rebecca Black and not familiar with Justin Bieber!

Well personally I love Justin Bieber and I dont like Rebecca Black but going back on what @spechless and @Bananaaddict said, I think Justin's songs are written really well. Rebecca Black's...not so much

i think biebs is okay, i have a couple of his songs on my ipod, but i'd rather listening to dying cats than rebecca black (no offense intended to ppl who like her)

I feel sorry for Rebecca.... that song 'Friday' really gave a bad impression.

Justin Bieber..Im a belieber forever!!XD

Atleast he got fans lol

Rebecca Black is a much, much better singer. Now that JB's voice has cracked, he can't sing like he normally does, it's lower and not as girly. Rebecca Black is a fantastic singer, it's just the autotune on her voice that makes her sound bad.

Rebecca can sing well without autotune. And Justin's voice kinda annoys me. And his hair isn't fluffy anymore!!! :P
