"I've been using your great tools to convert CD audio books into MP3 files so my dyslexic son can listen to them on an MP3 player with no moving parts. The tag editor and splitter/joiner make it easy to handle the often chaotic file naming and tagging of ausio book tracks, and the converter was very useful in changing WMA format files into MP3s for joining and tagging.
