Track Down's Playlist Join tool combines two of your own Spotify playlists into one brand-new playlist, with an option to remove duplicates (including remasters and re-releases) while joining — neither original playlist is ever modified.
Connect your Spotify account to choose two playlists to join.
Same connection also unlocks your listening stats.
No. Playlist Join always creates a third, new playlist with the combined tracks; both playlists you picked are left untouched.
Join creates a new third playlist from two existing ones. Replace overwrites one playlist's tracklist in place with another's — it doesn't make anything new, and it's a permanent change to the playlist you pick.
Only if you turn on "Remove duplicates while joining." By default every track from both playlists is kept, even if a song appears in both — turning the option on flags exact duplicates automatically and, with the same detection Playlist Dedupe uses, remasters, singles, and re-releases of a song you already have in either playlist.
