I created a LAN music server that uses Shoutcast. That way my family can serve our music library throughout our house on cell phones, PCs, smart TVs.
Until today, I only kept it to my LAN. But it is easy to port it out through my router. I have tested it on the WAN.
I do have limited outgoing/upload bandwidth.
Anyway, all of my music files are in mp3 format.
Might want to hold up on that. Because the copyright holders will find you... and bankrupt you. All because you can’t be allowed to compete with spotify, and still not pay the writers and artists for broadcasting their material without permission or royalties set up.
Just saying. Nice idea with the LAN, but you will be hosed if you go on the net. Want to with your own stuff you’ve published... great. And that would be a great idea for others who aren’t Taylor Swift or.....some other low talent waste of time.
