This is great! No need for the "music with kids" line. It seems inspired by the toys r us logo a little. The treble clef and bass clef are fine, but the other musical symbol is probably too obscure for the lay person. And the colors on the block are not perfect, but I have no concrete suggestions about that. I like the font of band of babies. If we don't keep it blocked in black, I'm not sure how it would look on white stationery, for example.
