ICYG Streams
Not being very up on AAC encoding, I didn't realize that at low bitrates (like the 64kbps target I have for ICYG streams), FAAC doesn't appear to perform much better than LAME MP3. While HE-AAC/AACplus would perform better and compare favorably with Vorbis, there's currently no free implementation of it available. Since Oddsock has stated that he won't link Oddcast to non-free DLL's (which I agree with), I don't see much purpose in implementing it at this point on ICYG and have removed the experimental AAC stream.
This leaves us with the ~64kbps stereo 44.1KHz Vorbis stream and the new 64kbps stereo 22KHz MP3 stream. If you're using the MP3 stream and have comments, please post them.
