here's a decent music player https://github.com/tramhao/termusic and for file management, midnight commander is an incredible tool https://midnight-commander.org/

Any of the TUI file managers. I use LF myself, but theres a few out there. You might even find it intuitive enough that you use it instead the regular gui file manager

termusic, superfile, fzf, browsh

lol basically and it's also hard to make decent crossplatform GUIs
