Updated for Spout 1.6.4.

Add a music loop system.
Use /playloop <URL> <Time before loop>

With /playloop, on first loading of the song, the song must be downloaded before played, but the timer will start directly.
So the first loop will cut, depending of your downloading speed, a part of the music. I just don't know how to catch the end of the downloading process at this point.

If you played the music once, the music will be cached, so the looping system will work perfectly, without cutting the first listening.
