Oh gotcha... that makes sense. I hadn't thought of the security angle.
Another question: is it possible to stop paying Apple for Spotify and then start paying Spotify directly? Can Apple just transfer your information to Spotify... or do you need to create a whole new account?
That's what I was thinking with the "why have two companies" comment. It just adds another layer.
If I can do everything through Spotify directly... then there's not another company involved.
It's the same reason I never create a new account on a website using Facebook or Google login. I want my username and password to belong to the site itself... not being passed through some other company.
I guess I'm weird like that
