I think she is not the problem. the music and lyrics of which she sings of are absolutely dreadful. In addition to this, the music video of which she is portrayed in is entirely pretentious and out of context regarding her age...
To be perfectly honest, yes, i agree it's a very stupid song, and people just need to get over it.
Also, the company that produced it, it's basically a company that that pay a buttload of money to so that they can produce a music video with 13-17 old girl, who has no musical talent, and is otherwise quite unoriginal.
Auto-tuning is used to make people's voices sound better, especially for those who can't sing. Either way, I dislike auto-tune in its entirety.
The problem with Rebecca Black is that her voice got auto-tuned even though she actually can sing properly. I saw some footage from Good Morning America and they showed an acoustic version of 'Friday' and I didn't think she was too bad.
