Spotify premium discord features free
Discord has a number of features related to music streaming that are "exclusively" available for spotify premium members. Notably, listening parties. To restrict these features to spotify premium, discord runs a few premium checks that we can overwrite.
Why does this work? Shouldn't discord not have these permissions for non premium members, just like every other app?
Discord has the ability to control the playback of music for non premium members so they can pause the music on spotify if they are talking too long in a voice call. Spotify could have exclusively granted permission to pause music, instead of playing, pausing, changing songs, etc, but they did not, presumably because they did not have the fine grained control and did not care enough to implement it.
