Description

When using youtube-dl to download a playlist from Bandcamp using an output template with the term "release_year", it does not properly rename folders to the actual release year. I'm guessing this has to do with youtube-dl creating the folder, then downloading the file, then reading the metadata as you can see from the log, and not going back to rename.

Identical output if you change the -o template to be "release_date" instead of "release_year".

Since the Bandcamp extractor already gets a hold of the artist name and album name, could the album release year information be gathered from there? If not, the date metadata is available and is successfully written to the resulting files and could be gathered from there.
