A withering criticism of toys that claim to teach music to babies. Is it accurate?

I saw this last night and I was wondering whether any parents here could chime in with their perspective and experience? I have a 3 month old baby and I'm interested in developing her musical ear as early as possible to give them the best head start I can.https://youtu.be/9DiHy5ZHzN0?t=2s via /r/Parenting http://ift.tt/2xBE8U3
