Say I want someone to listen to what I'm listening to in an uncomplicated way. What I used to do was give them the IP with an 8000 at the end (if I recall correctly) so they could listen to what I was "broadcasting" with Mixmeister.
Say, for example, I wanted to forget Mixmeister even existed. Is there a way I could use, for example, Winamp to "play out" mp3s and get someone somewhere else to listen to it?
