Merge playlists

[AmapianoRock]

As a user, I often find I make new playlists every week or month. When I make a new playlist I find that older playlists only have a few songs added or I have a similar playlist with songs I would like to add to my current playlist. Rather than adding each song individually I would like the ability to merge playlists together. This could be prompted with “Are you sure you would like to merge these playlists?”, “What would you like to call your new playlist?”  

This would also beneficial for more than one person if they would like to collaborate on a playlist, they won’t have to start from scratch. I have been wanting the ability to merge playlists together for a while and I’m sure there are other users like me.
