If you’re a masochist and have a managed switch, you can make do with a device that only has one NIC, by putting WAN and LAN traffic on separate VLANs on the same physical interface…

You can get a free subdomain from https://desec.io/ so maybe that could help? I did that for a while before buying a cheap domain. You’ll get something like stuff.dedyn.io

Whichever you go with, I highly recommend looking into https://github.com/NeptuneHub/AudioMuse-AI, which does analysis on your music so you can generate playlists/mixes from a specific song or from moods/genres
