I am developing an app using the spotify web api which sadly doesn't go with the terms of service of spotify, because it uses for example the logged in user's currently playing track. I am not that familiar with what is legal and what not in this context, so here are some following questions:
1) Can i legally sell the app on for example microsoft store?
2) Can i legally put the code open source on github and get money by getting sponsored on github?
3) If i apply for the commercial partnership from spotify, how long is the average waiting time and what exactly is the requirement for my app to get approved? i heared something like 6 month.
