I think you need a special domain for this project. I've seen someone didn't want to log in with their Spotify account because the domain a bit unreliable.
Love the idea, and the UX is great. Super simple to use, it quickly generates your "visual lineup", and I like that there's the option to adjust based on your taste from the last month, 6 months, and all time. Great work!
It's a great user experience which brings music, data and design together in a simple 1 min user experience. Check it out and put a smile on that face :)
