Hi Roger,
Life in never simple!  My choice of .opus was frustrated by lack of
support for my media server and author advises he will not likely be
adding .opus.

I therefore went with .aac as the next best option.

I now find that if I wish to include thumbnails I can only use .m4a (or

I appreciate thumbnails do nothing for sound but they do make searching
easier so looks like .m4a is the way to go.  Pity I just downloaded 18
files to .aac.

My only other comment for now is that the metadata that comes with the
download is very poor and very short on the info I have been used to.  I
think the problem is that whilst CD tagging is fairly well supported,
the YouTube videos are often prepared for a different audience but I had
hoped that at least the artists would be named.
If there are ways of improving this I would appreciate advice.

Thanks again.
