The Problem with Fragmented Lists
Over the years, you might have created "Study Music 1", "Study Music 2", and "LoFi Beats". Switching between them interrupts your workflow, and calculating their combined duration is annoying.
The Easy Way to Merge
You actually don't need a third-party tool for this; it's built into the UI if you know where to look.
1. Open the source playlist (the one you want to copy videos *from*).
2. Click the three-dot menu (...) under the playlist title.
3. Select Add all to...
4. A menu will pop up showing your other lists. Select your destination list (or create a new "Mega List").
5. Repeat this for all your fragmented collections.
Deduplication
Be careful! This method does not automatically remove duplicates. If you had the same song in two different lists, it will now appear twice in your merged list. To clean it up, go to your new playlist settings and select "Remove Duplicates" if the option is available to your account tier.
Analyze Your New Mega-List
Once merged, drop your new URL into a length calculator to see exactly how many hours of content you've aggregated.
