I always though of Spotify Lyrics to be a simple animation, it could not be farther from the truth, animating the lyrics based on time is quite a trivial task, but trnslation and time scroll synchronization proved to be very difficult to implement.
I had to write my own scroll logic as the Expo GO would crash, ScrollView had huge performance issues when an animation was taking place at the same time scroll occured.
