I have this 89 buck smart phone that can do this if you find the right app.
It can hold the usual 128GB SD card so that's quite a bit for little money.
I know a lot of MP3 owners that explode when we talk about why they died as a product line.
Sorry no I don't know of the right app but the hardware is all there.
I used to own a creative Zen jukebox with HDD. I Upgraded it to an 80GB SSD years ago and used it in my car for years. unfortunately, it's completely toast now.
What I'm wondering is if any MP3 players on the market still have a "car mode"? Meaning, leaving them plugged into their charger and removing power to the charger stops or pauses the playback.
I've Googled the heck out of this topic, but haven't come up with much. Any info is hugely appreciated, thanks!
