are you rooted? -> shutdown immediately, boot to twrp, dump whole eMMC/UFS
no root? -> try diskdigger app. free version only recovers photos. heres a crack from 4pda https://files.catbox.moe/l2gfmu.apk (from 4pda to/forum/dl/post/34080205/DiskDigger+Pro_v1.0-pro-2025-10-05%28163%29.apk , needs login so i downloaded for you)
why not use something web-based? there's navidrome for self hosting, or plenty of other piracy(?) music streaming sites (which some aren't sketchy, or safe enough to use with ublock origin)
if you can find one for cheap nearby, an ipod is decent. the full sized models can take large ssds and run foss rockbox fw. the price is insane in my area though so i can't have one, but my friend uses it and it's great.
