Well, yes, having a filename contain the information you need to find the file you're looking for is important. My issue here is not that I want to create useless filenames, but that it becomes extremely inconvenient to try and cram every last piece of meta-data into a filename; nobody wants to read through filenames that are hundreds of characters long, and many characters are inconvenient to place in a filename. (I hate having to escape characters in order to access a file on the command line...)

If possible, I'd prefer filenames that have a single, descriptive, and relatively short name, and then cram the rest of the metadata somewhere else. Audio tags might work well here; and if not, perhaps a small separate database of meta-data...

(And actually, I was interested in tags because they _would_ preserve metadata if the audio files were moved to another device, where filename restrictions might end up clipping data out of the filenames themselves...)
