I've actually done similar, moving sets of media files while renaming
& transforming them (id3v2 to set mp3 tags or modify
filenames/target-directories; exif/convert for .jpg files) along the
way and selecting them, along with container files (select playlists
for MP3s).  Sometimes the media files are named poorly, but better
filename information can be extracted from internal metadata, or can
be combined into things like photo-sets (rather than "DSC314159.JPG",
I can at least have "2013-04-01 Mom's birthday party 314159.jpg"
where the date comes from EXIF data, and a fixed string is replaced.

The idea of operating in batch on any data is pretty much always a
command-line win.
