There has been some dissent on having two themes being too restrictive in the competition. My intention was that it would be more interesting/fun, but if it turns out most people don't like it, then I don't want to impose it.
So, here are some options
1) 2 Themes going forward for all future round
2) 2 Themes for Round 4, but then change to 1 theme
3) 2 Themes for Round 4, but with the "type" of song limited to the top 4 options, then change to 1 theme
4) 1 Theme for Round 4 and all subsequent rounds
5) No Themes for any rounds.
