I’ve updated my ID3 tools (the id3reader module and the m3utree utility) based on feedback from people who tried them. Thanks in particular to Samuel Wright (11 email roundtrips) and Kris W. and Mark Williamson (4 roundtrips each) for making useful suggestions and being patient while the kinks were hammered out.

If you tried them earlier and had problems, try them again, and let me know if something is amiss. Sune Kirkeby also updated his mp3.py file to deal with extra information quietly, so you may want to grab that again if you had difficulty in that regard.
