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 .mp4). 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.
