This is gonna be interesting. So far, for the Dramatic album, the song that got the second highest number of votes in a round, got eliminated in the next round.
However Lost Not Forgotten, which came this close to elimination (just a single vote!) in the third round, might escape elimination if things end as they are.
We should check the other albums, I'd reckon that upsets are very few and that generally all songs that narrowly avoid elimination ultimely fall the next round, but maybe it happened more than I remember....
