Hello Bronson
I have alot of experience with what your talking about contact me if you need any more help, I've been running Shoutcast and Icecast streams for 15 years in SL and on the Internet. Contact me via inside SL I'll give you my Email address run your Bit rate on the stream higher then what the music was recorded at, If your music is recorded at 128kb, then run your encoder at 192kb so it dont Choke and cough. MP3s have been changed as to how they are broadcast and listened to, But they can still be broadcast without https. They can still be broadcast as http.
Thanks
