Okay, I can see what Polow whatever was getting at, but Ciara is definitely not an Aaliyah replacement, although she's not a bad singer. I really don't feel like Ciara is trying to copy Aaliyah, because they do have different styles; Aaliyah is sultry and coquettish, and focuses more on heartbreak, whereas Ciara is more dismissive, tends to boast, and hardly ever employs 60's soul vocal techniques. As far as singing goes, Aaliyah has the slighly thicker and more seasoned chops, but Ciara has some ideas of her own (like her opera-like vocals in "High Price"). Aaliyah wasn't exactly a Whitney, a Toni, a Mariah, or a Mary (even though her intonation and agility was better), but I appreciate her as an vocalist because she was a risk-taker. Alot of times the risks she took vocally didn't work but when they did the results were notable. "I Can Be" and "What If" imply that Aaliyah sounds better as an alternative rocker than she does as an R&B artist, and "Never No More" makes domestic abuse sound enticing. While I enjoyed the "One in a Million" album, her self titled release is when I think it all started clicking for her, although "Try Again" and "Are You That Somebody" are two of the most successful tracks of all her unconventional efforts.
