Renaming mp3s fails on Windows if using ID3 tags.

[Boggart]

Trying to rename a folder full of mp3 on Windows 10 using ID3 tags results in the following error for every file: The process cannot access the file because it is being used by another process. Using a file handle viewer, I was able to conclude that no processes actually had the files open and by trial and error, I discovered that it was the use of ID3 tags to rename it that was causing the error. f2 -r "{{id3.artist}} - {{id3.title}}{{ext}}" -x
