Well I don't really listen to a lot of fully instrumental bands, Pomegranate Tiger and Intervals being the exceptions (Intervals even has a singer in their newer stuff I think), aswell as one or two AAL and CHON songs, but I kinda left the option open to do an instrumental round, which I'll probably end up not doing, because I want to create competition through rating your best possible submissions, without setting too much boundaries on what you can and cannot send. I'm aware that this round kinda does that, but I'm more interested in 12 uplifting/happy songs than 12 instrumentals at once.
Which brings me to my next point which is kinda for the same purpose, I don't want the roulette to be revolving around a solely technical approach of saving certain artists or songs for a potential themed round which you're not even sure of, so at the very least, here's all the rounds that have a theme, shouldn't be too much of a mystery to figure them out:
Come To Life - Round 5
Goliath - Round 6
The Root Of All Evil - Round 8
This Is The End - Round 10
