One year ago I stop being able to add more songs to a playlist which almost reaches the 10.000 tracks (9956). I supposed that this was a Spotify limitation, so I started a new playlist. But now I found that I can't add more playlists or folders to my account, and there is no way to solve this, except creating a new account. Is there any limitation in the number of playlist and folders into one account? Is there anyway to workaround this issue without using a new account?
