I'm creating playlists programatically and I was wondering about the limits. I read that only 10.000 Songs can be saved to one playlist/all playlists together. Can anyone clearify this for me? How many songs can one playlist contain? Does this include songs, which are added multiple times to one playlist? Is there a limit of how many playlists I can create on my account?
The only "official" thing I see is that your documentation states, that the theoratically last playlist you can get is the 100.050th, as far as I understood.
