The only requirement is that the song title and file name match. I want to keep this feature fairly simple in nature, so I'm not going to allow the master to load other songs on other tablets, because that would start getting very complex, very fast (and require much more complex UIs). With setlists, the only requirement is that the setlist name matches. If the two setlist contents don't match, I don't check that, so in theory you could get away with loading different songs on different tablets that way.
