In terms of the "vocals' that some people are talking about, I don't think Ciara OR Rihanna can sing that well. However, Ciara's voice is somewhat more pleasant on the ears. My opinion though. These artists don't depend on vocal prowess, but on putting on a show. If they just stood there and sang, it wouldn't be so great. Not saying they can't sing, but they just aren't the best. Regardless, Ciara KILLED these performances, and I'm sorry to hear she did terrible on sales, but she's still relevant, and she's not going anywhere!
