Yes, I applied, was accepted and was there several months. Only that I was discouragd because 95% of the time it is about people complaining abot things that is ither impossible to answer ("is Spotify better than Tidal ot Qobuz?", "why is S not working") or things that could be answered with 3 minutes googling ("why is X-artist not on Spotify").
After some time inactive, my account was deactivated, what is a pity, since as you said, I wold be glad to answer every now and then when there is a *well-formed question*.
I would like to join the spotify rock star program aswell! Been a long time user and a premium user aswell! Love the app and i always recommend spotify as the best music app out there! Thank you and i hope to be a rock star!
