You contribute to a song and you get a credit, it’s simple.
You write 3 songs, you’re credited with writing 3 songs.

It’s not a points based system like a game or a token. It’s just the amount of contributions you’ve made.

The idea would be that someone who has been credited on contributing to 3000 songs may be more experienced than someone who had 3 song credits. That’s it. The point aren’t worth any monetary value, it’s not reddit or a video game.
and no, nobody in the music industry goes around in a dick **** measuring contest about their credits?

You thinking way too much into it and you’ve outlined an extremely small detail that has little relevance to the product

as for the website, they’re credits are officially sourced from the music companies, Sony etc.
Not everyone can get the major music label to give them the credit details of all their music. That’s why nobody else has done it.
