User description

Sometimes when I try to open a song, the app either crashes, or the loading never ends. In the latter situation, I am forced to reload the song. Sometimes, when I'm playing a song, the video will pause out of nowhere, and it won't unpause for a moment. The video may also skip a few seconds ahead of me and pause, in that case, it will only unpause when I correctly play all the notes up to the moment where it paused.
