In my (seemingly never-ending) quest to get music into my car like a Regular Person I found that if I fill a USB stick with audio files in Artist/Album folders my car's audio system will occasionally work right. The script Export to Album Folders does this. Then I realized that I had a lot of Apple Lossless files which I'd have to convert to MP3 before dumping them to the stick. But that leaves the superfluous converted tracks and their files in iTunes' library which I'd have to remove using my hands.
ConvExp to Album Folders (Convert and Export to Album Folders) takes care of converting selected tracks, moving the converted files in Artist/Album folders to a selected location, and removing of the converted effluvia from iTunes.
A couple of Correspondents inquired about doing something like this, so I hope they and you find it useful.
