Which mp3 player supports the "play on start" function?

Question

Mobile devices

I'm looking for an inexpensive mp3 player, or maybe a board with the function of turning on music playback when power is applied.
Purpose: when you turn on the light in the bathroom, automatically turn on the music.
Ideally, I would buy a ready-made solution, but you can also assemble it yourself, no practical advice was found on the Internet.

When you press the power button, it starts playing, when you press the power button, it stops. When you press the power button again - it starts playing from the same place where it turned off.
