Pretzel's free tier is non-interactive. Upgrade your experience with Pretzel Premium.
What is non-interactive?
Non-interactive means that some of your features using the free tier of Pretzel will be limited. While you can skip tracks, and rewind a track to the beginning, you won't be able to seek ahead within a specific track (e.g. say, to skip 30 seconds of the song).
