How to remove duplicates from youtube playlist? is there any tool/ site to scan for duplicates in playlist automatically, then remove them?
You can do it by opening the playlist in YouTube (not YouTube Music). If you then clock the 3-dot-menu and select "Settings" and then "Advanced Settings". After that a "Remove Duplicates" appears on the right which you have to click until it doesn't find any duplicates anymore.
This seems to have worked for me. I still hope there will be a better integration in YouTube Music at some point.
It is described in detail here.
