I'm going to carry the use of CSV metadata a step further.

First, I'm currently finishing a tool that reads iRealPro data and formats this into a nice PDF. iRealPro songs contain a limited amount of metadata like title, composer, style, key, and tempo.
If the iRealPro data contains an iRealPro playlist, I produce a multi-page PDF document and the corresponding metadata CSV. In other words: a Fakebook plus index in one go.

For reasons not relevant here, my tool can also produce PNGs instead of a PDF. This brings me to the feature request to extend the use of metadata CSV for other imports (in particular, batch inport) as well.

For example, I have a folder with ChordPros or PNGs, each containing one song. I can batch import this folder, but it would be very nice if I could place a metadata CSV in the folder (or specify on the import dialog) so that all imported songs can have some metadata filled in.
I even think that given how far Mike already implemented support for metadata CSVs this won't be hard to add.
Implementation hint: Add a "filename" or "pathname" element to the CSV to match a file with its metadata.
