What about listen to music with no ads and not paying ransom for your ears? =P

I got tired of paying ransom for my ears and decided to use a Raspberry Pi to be a music player on my LAN (it has native mDNS) with Bluetooth support and a web interface to control song playback. I've been using it for about 6 months and it works well for me. I made a tutorial on how to embed it. To whom may concern, the core of it was written in golang. I know, nowadays, listen to the music with no ads and no ransom it is veeeery, very cringe! Haha!
