how can i self host my music?

hello,

im really tired of google music and spotify, and want to self host my downloaded music and create my library.

however, i know nothing about self hosting. My knowledge is absolutely zero. And Im completely lost about how to self host my own music. Dont find any good tutorial for dummies and i have a lot of question. I dont understand nothing. I see the tutorials of Navidrome and Ampache and still understand nothing. All of that looks extremely complicated to me.

How can i self host my music? I need to pay something? A very old and slow pc is enough?

Im completely lost. If someone can suggest something - like a tutorial , dunno - to build/self host my own music I appreciate a lot.
