I really like all of these - #61 is my favorite because of the swirly piano keys, but #64, #62, and #59 are really good. I like the fonts - fun and flowing. The yellow "O" I think looks a little like a sun and is a little too eye catching for me. I have to show #61,64,62, and #59 to some people - they are all really nice for different reasons. Thanks!
