No, still don't have the multiple genre thing solved. Did, however, formally put in the requirements for ONE or MORE of the following: ffmpeg (for ffprobe), mp3info, or exiftool to get song duration and artist information from the MP3 proper. Fixed a bug around mpc's output and the pausing mechanism. Also fixed a bug about duration, where duration was greater than 1 hour but less than 1 hour + SONGLENGTH. Thanks to Steve N. for pointing me at a lot of these.
