just made it for my baby, used an NPN transistor (base to D4 via 1k resistor, emitter to ground and collector to vcc via speaker) as amp with a small 8ohm speaker for switching instead of tactile switch, used a TSOP1738 IR sensor (+ to vcc, Ground Gnd, signal pin to D2), use any IR remote click any button u can Play the music. Happy Parenting.
