Probably not very easy to do, either.

There's "Export to XML" and "Export to CSV" (or thereabouts). I want "Import from XML" or "Import from CSV".

Just a way to change attributes (title, artist, source...) from a loadable file. I could in that case run something to redo capitalization, or do a database lookup and populate years, or something like that, and be able to upload the data other than by hand.

Just an idea, and quite likely not one worth pursuing.

If anyone else finds this useful it really wouldn't be too hard to do ... Basically you would have to have the tunes already uploaded and I could just import the replacement tags from the file... I would probably use TMS's XML format if I did it ..

Right, that would be the idea. You have the tunes and just replace the tags with the imported XML.
