I made a music playlist awhile back. This morning YouTube showed a message saying “1 unavailable video hidden.” You can un-hide hidden videos, which I did. Can you tell from the picture which of these three videos is no longer available*?
YouTube won’t tell you which of the videos in your playlist is no longer available. Got-damn.
*It’s the Tom Petty video, btw.
You can copy and paste the video URL into the Wayback Machine, if it’s decently popular there’s a good chance the title and maybe even the video itself is archived.
That is what I try to do. I search the Youtube ID and sometimes Duckduckgo will spit out a title.
