Is your feature request related to a problem? Please describe it

My problem is related to bug #5557 causing several duplicate entries in Playing Queue

How will you/everyone benefit from this feature?

1. Trying to create master playlists with hundreds of songs to shuffle, it becomes increasingly more difficult to tell which ones have been added to the list
2. Would be useful for creating a playlist out of multiple playlists without having duplicate entries. ie: "Nonvocal Liquid Bass" and "Beethoven Remixes" could be combined for whatever study music you're suddenly in the mood for, but if they had overlapping interests (and thus, some of the same songs), you would have to manually remove those entries in order to not have them in the list multiple times. This could be especially bothersome, again, if you had a lit of songs in each list.

(To be clear, I'm referring to songs of the same ID -- removing entries with similar titles would be a different issue)

Have you looked at #5334 ?

Have you looked at #5334 ?

I didn't notice it, although I had tried searching for something similar. I would consider this a separate feature since it would apply to preexisting entries, as opposed to checking one at a time at the time of adding them to the list. Plus, #5334 wouldn't apply retroactively.

I can try implementing this functionality.
