Unfortunately, this was just a fun project for me to learn web development, and it is currently not available to the general public. I am working to get approval from Spotify to make this publically available; however, there is no guarantee that happens at this point. If you think this would be useful for you and you would like access, send me an email at [email protected] with the name and email that you signed up to Spotify with, and I can grant you access. If it garners enough interest, I can continue development and add more features, including the ones mentioned on the home page.
