Foobar2000 has a replay gain scanner system that can scan your files and add a replay gain tag to them which a music player can use to normalize the loudness.
Audacious allows you to open a folder and play all files inside and has replay gain support.
But nope it's just things that I noticed (checks calendar) a long while back when I was looking at getting a bunch for my emergency kit.
I decided against buying them as they are an order of magnitude more fragile than an LED light, no guarantee that they will work when you need them and a ~4 years of shelf life compared to ~10 years for lithium batteries.
Modern LED lights can offer days and even months of runtime on a battery set, multiple light output levels and when paired with a lantern cap accessory or a cone of printer paper provides the same functionality as a glow stick while being far more versatile.
Plus combining several sets of rechargeable batteries, solar panels and charger you have consistent lighting for at home and having the option of keeping lithium batteries in your evac kit.
Unfortunately you are going to be massively disappointed.
There is going to be a massive variation of runtime, light output and reliability.
The things that will cause problems:
Quality of manufacture - The runtime, light output and reliability will vary wildly depending on the manufacture and country.
Size and shape of the stick - There is about 5 common shapes & sizes available that will affect the light output and duration
Age (from date of manufacture) - Glow sticks degrade over time causing shorter run times/light output
Packaging - Light and air intrusion can degrade the chemicals causing shorter run times/light output
Temperature - Glow sticks stored in higher temps will degrade faster and will accelerate the chemical reaction causing shorter run times, colder temps will impede the reaction greatly reducing the light output.
Storage - How they are stored is going to affect how reliable they are (rough handling can crack the glass vial &/or cause the stick to leak)
Colour - Each of the different colour variations will have different light outputs.
Stated runtime - Sticks commonly come in 4/6/12 hour versions (other duration available) shorter run times will be brighter but the longer runtime sticks will be less bright.
So to do tests you would be needing to test thousands of glow sticks at minimum to get anything close to reliable numbers.
It is a measurement of the files audio volume against a set level. Then the file gets a tag (metadata) for the volume adjustment.
To put it simply: ReplayGain turns up the volume an appropriate amount when playing a relatively quieter song/album and turns down the volume an appropriate amount when playing a relatively louder song/album.
Pretty much any music player should support replaygain including VLC.
Rather than trying to get your idea to work you would be better off getting a cheep WiFi access point as they often allow you to connect it to a wifi network and pass it through to wired devices via ethernet (bridging).
Some Wifi routers have a setting to allow it to be used in bridge mode as well.

You have been staring into the void for too long.
You have two problems (three if you count MP3's).

Try putting a flat bed or a folded up towel up there & see if they like it.
Looks like a standard issue orange cat.
I thought that was the dolphins?
Looks all normal to me.
Cats view the laws of physics as a mere suggestion.
Are you sure it isn't μ?
Gee thanks for calling me an AI.

I have had more than decent success with Orico devices.
Here is one that suits your needs:

I can't say that I haven't thought about audio volume correction for streaming audio.
There must be a way of doing it as Spotify and other services have a version of replay gain.
Replaygain doesn't change the file itself.
It is a measurement of the files audio volume against a set level. Then the file gets a tag (metadata) for the volume adjustment.
To put it simply: ReplayGain turns up the volume an appropriate amount when playing a relatively quieter song/album and turns down the volume an appropriate amount when playing a relatively louder song/album.

You will want to use something like Foobar2000 to scan the files then write replaygain metadata to each file.
Then you enable replaygain in VLC and it should work as you want.

That's not a look of "I've been caught".
That is a look of either "Oh look prey, must hunt and kill" or treat bag has been opened
