I don't know if I can choose just one, so here is my list to honor the artists who are horrible singers:
Gwen Stephani: Rich Girl. Ok, it was cute when the little Russian Jewish guy sang the 'If I was a Rich Man' in Fiddler, especially as his goal was putting staircases all over his house. But Gwen, in case it escaped your notice, YOU ARE RICH. Go back to your band because you suck alone.
Britney Spears: Toxic. Was the violin player playing like he had his balls in a vice on purpose? Britney's voice has never been excellent, but waking up to pair of cats caterwauling would be more pleasant than listening to this song for more than two seconds.
Good Charlotte: Lay It Down. Seriously, does off key high-pitched falsetto count as singing? Is selling out to make more money worth it? These are my two questions for the band.
Ashlee Simpson: La La. She blames the Orange Bowl sound system for being bad, I blame the singer. When do singers feel the need to sing only flat notes in their songs? I am not sure this is because that's the way the song was written, because I am positive I could sing better - and those of you who have heard me sing know what I mean... Sign the petition to make her stop singing, I don’t know where on the web it is located – google it.
