Music in the bathroom
 

Hi everyone!
Please advise, with what sound equipment can I play music in the bathroom by turning on the light switch?
This is when you enter the bathroom, click the switch and music starts playing (looped playback of a specific track from digital media source), and when you leave the bathroom, you turn off the light and music with one click.
This should be a system that can be hidden / built into the ceiling or wall of drywall, in combination with moisture-proof speakers. But not a Bluetooth or smartphone control, not a smart light bulb with a built-in speaker and not a radio alarm clock;), it should work simply by pressing a switch / power on the device.
Thanks

...you could start to sing when the switch has been turned on. Simple.

:) :D :) :D :)

Please do not turn topic into a circus! I did not come here for jokes! Please answer purely on the topic and competently!
It's a design project and I have found some solutions on the web but it's more unprofessional, impractical and unreliable.

I need more practical and professional solution.

You started it :D

I used something similar to this in my boombox:

When powered up, with a sd memory card (mp3's) , it will start without user intervention.
you will need a photo detector to switch power.

(and an amp & speaker of course)

If you really think it's a joke just go to Italy, Bologna, Cersaie international Exhibition of Ceramic Tile and Bathroom Furnishings and you will be surprised what limited imagination you have.

How about a camera too..... YouTube

I need something without Bluetooth or remote control. And no need a photo detector because it will be powered on with the light switch. Like here: YouTube or here: Auto-Play/Stop Music (MP3) When You Turn Lights On/Off | Abdullah Yahya

You should probably do your own homework and/or develop a sense of humour.

That said, there are some options here that might be of use: Audio Boards - SparkFun Electronics

In particular the QWIIC MP3 Trigger would be easy to implement - it also has a built in amp which would reduce module count.

Switching modules on and off repeatedly would probably be more detrimental than just letting one sit in low power state and triggering it with a photo cell. The module I mentioned has to go through a load sequence (how long that takes is yours to find out) and can be triggered by pulling pins low. You might get away with switching it on and off and having those pins permanently tied to ground.
