The idea of this was to have a little fun with a few songs that both Neuro-sama, and Evil Neuro have each sang individually (as in not a duet together).
I have synced togther their performances, but isolated each of them to one side of your headphones! You have to listen in, and see if you can tell which of the Neuro twins is on which side!
(I was told to post this here, so hopefully that's okay!)
First Track: The Phoenix (Fallout Boys)

Fourth Track: Perfect Machine (Starset)

That's all of the tracks for now!
I'll probably give this a few days before revealing any answers so that people have time to play along if they want.

Their voices side by side like this makes the distinction pretty noticeable for me, I could hear which is which within a few seconds
