Hey there - Love the simple feel of your logos, but I'm thinking we can spruce them up just a little bit more. I would say that 22 is my favorite. The color scheme feels right, but I feel that the logo is missing a "playful" element to it. Feel free to disregard the coin concept in the log if you think it is holding you back. Thanks!
Also, can you do version of #51 in different colors, including the colors #ED1F51, #0A3542, and the U with the dots, make them look like boy and girl listening to music? Keep the simplicity though.
