6 EUR per month really ain't much but then 80 GB of SSD is really not much for a media library.

FWIW I both rip, losslessly and verifiably, my own CDs to FLAC (lossless but compressed), I run Plex (tried JellyFin and going to switch) and yet I still pay for Qobuz (I don't see why I'd pay for Spotify when lossless streaming services like Tidal and Qobuz do exist: additionally Qobuz allows to buy DRM-free song individually).

Now, and that is not a snark: I both rent dedicated servers since decades now and run Proxmox at home.

I thought "self-hosting" meant hosting on your very own hardware, at your place (e.g. from your home).

If hosting on a rented virtual server is "self-hosting", then I take it hosting on a rented dedicated server is self-hosting too? But then what's the difference between a company renting servers and deploying its apps there? That one is registered as, say, a LLC and that the other is an individual?

So "self-hosting" depends on whether you're an individual or a company?

Sounds like a weird definition of "self-hosting" to me.
