YouTubers like me use Auto Library (https://www.youtube.com/audiolibrary/music) inside the YouTube Studio frequently. Since there are hundreds of amazing audio files to explore, it is really hard to keep a track on which ones we have played already or we haven't.

For now, I play some of them and then Star them so that I know which of them are played.

The ones I like, I download right away ( specially the ones which doesn't require any attribution ) - makes things easier for me.

So besides having single star for tagging, having one more star to let us keep track of our choices.
 

What if tomorrow I have to check out more audios, how am I going to know which ones I have played so far.

Then perhaps, instead of having 2 stars, just mark the already played ones with “PLAYED” or something that helps us distinguish between the Played and Unplayed in the Auto Library.

Above are the pending audio files which are yet to be played. There is no way to know which ones I have played so it wastes a lot of time.

Having this feature will definitely help a lot of users.
