If you can show that the rest of my message is in any way wrong I'd
*love* to see it.  I'm eager for my own project to easily and sanely
parse track info (title, artist, album, track number and length) from
all of the common formats (mp3 + ID3v1,2,3,4,ogg,etc.).  Until I see an
actual elisp example that contradicts my direct experience, I'm going
with what I've observed.
