I think it would be great if songs that failed to play would automatically retry or skip without user interaction. As it currently stands, when I'm out and on cellular data songs will occasionally fail to play. After waiting to see if it's just loading, I have to pull my phone out and manually/retry skip, which can get annoying after a few times.
Perhaps it could be a setting to choose how to handle failed songs, but either one would be an improvement over manually choosing for each instance.
I mostly listen on the android app, but I believe this happens in the web player as well.
