Of course not. You need other software to rip your music from physical media, or potentially multiple other software to search and download them. You’ll need additional software to host everything over the internet. You’ll probably want a computer to act as a server. You’ll very likely need a private VPN to be able to access it over the public internet. You’ll need some networking knowledge to set everything up. Hope you’re familiar with docker. And afterwards you’ll have to manage everything yourself once they are up.

Even if you don’t search for new music very often it’s a lot of work. If you care about being able to discover new music then it’s pretty bad. There’s a reason music streaming exploded in popularity so quickly. This shit is not easy or convenient to self-host. At all. If you’re already selfhosting a bunch of stuff, then it might be worth it to add this stack on top of your existing stuff. But absolutely not worth building anything from scratch just for this.

Nobody’s gonna dispute the necessity of some sort of server somewhere in the mix. But does it need to be something like PSN? A central 3rd party service that most games only use because they’re forced to?
