I listen to FLAC's mostly (high quality, loseless audio files - CD quality or better) most of my collection has come from ripping CDs I owned or checked out from the library or albums bought on bandcamp, quobuz, and ototoy.
I use Rhythmbox to listen to files on my PC (Linux) - I think they have/had a Windows port at some point. VLC works too but is more cumbersome for large libraries on desktop IMHO. But VLC is actually pretty good on Mobile (iOS/Andriod.) besides the pain of syncing files over to iOS.
I splurged on a dedicated DAP (Digital Audio Player) last year that I'm mostly happy with: a HiBY R1 (my two complaints are: 1. for whatever reason it refuses to pair to my car's bluetooth, no issues pairing to numerous other devices. 2. It doesn't remember what you were last playing when it shuts off.)
