Is there any sort of PCB out there that will store just one song and only play that song when turned on? I'm trying to build an electronic music box, and need to get some sort of PCB or music player that is small and will allow me to put the song of my choice on it. How should I go about this?
For the last 10 or 20 years, there have been IC chips that could store and play audio. (I think I have one in the attic). Many children's toys use these chips. But I don't know what's available now.
Just use one cheap MP3 player with same file playing.
Feature not available on cheapos, record as many files of the same song on it and play.

There's digital door bells that allow recording custom sounds. Probably a car alarm.
Now, one MP3 player family that might work is the old RCA Lyra. Pushing "play" once would make it wake up and play right away. They have an SD/MMC slot (good for up to 2GB), varying amounts of built-in memory (64M to 512M mostly), and run off a single AAA cell. Wire up an external D cell, and battery life should be near infinite. Check Amazon to see what the RD1028 looks like (if the picture I linked doesn't last), then search eBay for RCA Lyra; there's a couple there when I looked just now, but not listed under the actual model numbers. Or check out local pawn shops. These were one of the most cost-effective flash players at the time, and the (undocumented, probably because the idea of that much flash was just crazy talk at the time) support for 2GB SD cards means they're still useful.
