I've downloaded this song from the si.ple song collector but it does not show up in my library and I cannot figure out how to add it to the walkout app. Everyone wants this song right now. I'm wondering if it's because the title begins with three periods.
Try the latest update for the song collector here:

That issue was fixed back in June of this year so the update should get you going.
