Navidrome + Substreamer, but I’m starting to use the Navdrome webapp as my main player - it links into the car’s volume and next/previous, and works very well. On your desktop you can install it as a webapp with an icon on the desktop and a separate window.

I also have metube which drops songs directly into my downloads folder.

A regular shell script to create playlists from each folder, so I can arrange songs onto folders and get playlists.

Can share a playlist or song anonymously, or add a user to the system

Amazingly simple, powerful and complete.

The chip choice depends on what you want to do with it. Streaming may need a better graphics capability (may, or may not depending on how you generate the stream).

The choice is between th ei7 2nd gen, or the i3 4th gen.

• The i3 is lower power consumption: 54W vs 95W. A big difference.
• They are about the same single thread performance, so no real difference.
• The i7 has much better multithreading capabilities, so this may come in handy for the multiple streams. It has 4 cores, 8 threads vs the i3 2 cores, 4 threads. A big difference.
• Both use DDR3, and the i3 can take slightly faster memory, but not a big diffrence.

So, I’d be going for the i3 if power consumption is an issue. Otherwise the i7 may give you better CPU capacity if you run more than one thing at a time.

Either way, you’re going to love the journey.
