How do you manage your music library?

I have a giant Spotify playlist with 5000 songs added to it. I frequently scroll through it randomly to be transported to certain times in my life. I don't really categorize music, and prefer one massive list.

As for other ways of listening to music: I have downloaded loads of 'binaural beats' for concentrating when coding, and lo-fi or ambient music for focus too. I got those with YT-DLP[0]. I downloaded because having a browser with Youtube open gets in the way of webdev. I prefer to have VLC in a separate process playing downtempo music.

So not much categorization in general.
