I have added few more features:

• get the list of playlists in a user profile
• check if there is an empty playlist and if yes, get its 'id'
• if no playlists exist or if no empty playlists exist, create a new playlist and get its id
• time taken to execute the program completely

This way we can have new playlist on every run.

Note: Spotify takes some time to report the proper track count in a playlist. So, if you create a new empty playlist, add some songs to it, and immediately run the code again, the previously created playlist will be reported as empty. I think it takes roughly 15sec to get the updated count.
