David C vs. David A. I've started to analyze these two. David C has swept everyone off of their feet by singing a different version of very popular songs. He has made me stand up and cheer just like Randy did. However, what is going to happen when he starts singing songs that nobody knows? So far, the songs that he has sung that haven't been popular have been just ok. He can be very successful at re-arranging old favorites and making them more modern. On the other hand, David A has a beautiful voice. The not as popular or unknown songs that he has sung have succeeded due to his pitch perfect voice and connecting with the audience with his inspirational personality. Both will be very successful. However, I give the edge to David A due to his voice and turning every song he sings (popular or not) into gold.
