Your Spotify numbers seem spot on, but the other services seem WAY high based on the research I've done. I'd love to see the raw # monthly listens or monthly listeners per service. How are you calculating the other services? They also seem WAY high looking up my own music vs my actual pay receipts 🤣 https://royalties-calculator.com/artist/life-toward-twilight/0TNktgj3DeKEThrUbgq6sb/
I put together a calculator that is slightly different here: https://danieltuttle.com/how-much-money-will-you-earn-from-spotify-streams/
I suspect Apple Music numbers are way up from the McCandless research I used as my basis, but otherwise I'd expect the ratios to be similar across platforms.
Your general UI/UX is amazing, though. Good job!
