The game thinks the songs have downloaded, but it's obvious that the songs don't download because they finish downloading instantly. The song doesn't play when I'm in the level. I went into my local files and found that the game downloaded an MP3 with nothing on it rather than the song. I don't know if anyone else is having the same problem as me, but I can't find a solution that works anywhere. Whenever I see something that isn't directly related to my problem, I try it anyways just in case, but nothing is working.
