I looked pretty hard - I specifically don’t want an android OS called an mp3 player. I want a dedicated media player that has physical button controls (not touch screen), is very snappy, has a good UI, and has a purpose-built OS specific to only playing songs and podcasts, and maybe movies, which I can sync with my computer (maybe with rsync or whatever else). No apps.
The only option that I could find was an iPod classic, modded with an SD card and better battery.
If something else exists, especially brand new, I’d love to know! But I couldn’t find hardly anything that wasn’t just an Android phone with no cell service.
This is a problem with "single-purpose" devices for kids, too. Drawing tablets, music players. They're all actually full Android phones (sans cell modem) and tablets. It sucks.
Pretty sure I know what music player you're talking about because I have the same requirement.
Sony's modern Walkman is an Android device. No thanks.
I can't vouch for it personally since I don't own one, but I saw a video on YouTube mentioning the Innioasis Y1[0], which supposedly does a decent job of replicating the iPod experience with some modern features like USB-C and Bluetooth at a decent price. Can be flashed with RockBox. No external SD slot, but it can be opened to swap out the SD card it comes with. Reportedly doesn't feel nearly as nice in hand as a real iPod does but that's pretty standard at this price point.
Yes, I want these for my kids so very badly. They have Yotos (similar to Tonie) for bedtime, and iPads for school work, but those are not ideal for a number of reasons. I want them to be able to experience music like I was able to with an FM+cassette walkman clone in the '80s and early '90s, or with my Nomads and iPods in the late '90s and early aughts. Hopefully someone here can suggest something!
ETA: OK, there are quite a few highly-rated options on Amazon, so I just need to solve the "putting music on there" problem and the "dropping it and immediately destroying it problem".
Not sure if this would fit the bill for you, but I really like it:
96GB Mp3 Player with Bluetooth 5.0 - Aiworth Portable Digital Lossless Music MP3 MP4 Player for Kids with FM Radio HD Speaker for Sports Running Super Light Metal Shell Touch Buttons (Actual Amazon description)
The "touch screen" is only for moving around the menu. The menu is easy to remember. Sound quality is really good and it takes a mini SD card. Right now, $40.
Swofy makes a little media player that has physical buttons; the crowd here at home really likes them: https://a.co/d/9icRCCs
Not sure why you want to have purpose-built OS as the hill to die on since many of those Android-based mp3 players absolutely outclass the old iPod classics in snappiness and compatibility and output quality.
Plenty of choices that meet your other criteria once you're OK with it being Android powered.
Like a SnowSky is very obviously stripped down Android that can only run the music app it's shipped with, but it's otherwise everything you want.

There are a lot of DAPs in this style. They're just not popular because the Android-based units are perfectly fine and don't feel like Android phones with an MP3 player app installed. Most buyers don't have arbitrary OS requirements, they just want a device that works well.
I'd start by looking at the Rockbox compatible devices list: https://www.rockbox.org/
