Why? Binary Music groups. Select, copy, then paste into Apple Music search or filter field or finder spotlight to see if you already have it
I don't understand why I haven't added this already. Noted and will be there in the next release.
Starting v0.64.6 you can copy filenames, subject and poster name to the clipboard. Is this what you wanted?
Not exactly, I was thinking drag to select bits of each, but your way is better. Copying a whole list of subjects at once is perfect!
