Its my impression that after getting a rare song that it will, with 100% certainty, turn up in the encore of the next event if one does well enough to qualify for it.
My questions are
1. Is this true?
2. And, does it turn up as the 1st or 2nd encore song?
If its always first encore then by mastering the rare tracks each time between events (maybe under a different profile) then one should be able to get all six rare songs in just 6 sequential events.
Edit: Of course the song won't be there under a different profile, but that's not the key point here.
Anyone confirm or deny?
