I don't know what it means. My dad gave me a gift card and it is not working, this is going on for weeks now, and I'm talking to some guy from Spotify on Twitter, and he said he was going to check backstage, and then I did not anything more for almost a week.
So I figured ok I'll go into my account and look at the stage to see if anything is different or if there is somewhere to enter the gift card but there is no stage anywhere in my account. Is he talking about a real stage at the spotify office where they play the music??
