Hmmm... I probably have eight different versions of "Take The 'A' Train". And, they're all spelled slightly differently. Are those single quotes or double quotes. Etc, etc. I don't think I have a single track called "Mother".
The wonder of jazz "standards": every CD I buy tends to have at least one "standard" on it. After a while, they all add up.
Stupid feature request: When you're doing an "advanced" search on titles, it would be nice if the EMPEG collapsed together all these slightly mutant spellings of the same song.
