YMMV: Rebecca Black
Acceptable Target: Though opinions of her may have somewhat changed, some still make fun of her as the girl who sang "Friday".
Hate Dumb: From the YouTube comments on Friday alone, it's evident that many people hate Rebecca Black for things she's clearly not responsible for. And what about those awful death threats and trash talk that made the poor girl cry?
She sang "Friday" without autotune. She is actually pretty fine as a vocalist.
This video shows that she has a relatively decent singing voice.
I Liked It Better When It Sucked: plenty of people loved Friday because it was so horribly bad. It had terrible lyrics and overly autotuned vocals with generic pop music. However, "My Moment" was considered by by the public to be... listenable. It didn't have nearly the amount or cheesy fun the original had and was just not fun.
Misblamed: The lyrics and the abusive use of auto-tune were actually done by Ark Music Factory, the company that produced the music video, not Rebecca Black herself.
Though from the other wiki, she did chose this song, despite her mother's doubts. Rebecca's reason is that all the other songs are about adult love, which she haven't experienced it at her age at that time.
The Woobie: After Friday, the backlash hit so hard that people were bullying her in real life, with some going so far as to sending her death threats. She eventually turned this around by going on to donating the profits from the song to Japan's relief fund for the 2011 tsunami.
