I voted! Listened to the tracks many times to make my decisions.
On wildfire vs halc I went with halc mainly because the arrangement was more varied. Both songs are pretty good, fun arrangements and nice vocals. wildfire shows a lot of progression in the vocal production from Round 1 too!
On Hakstock vs Amphibious I went with Amphibious because I could recognize the sources more easily. Again, both songs are very good, Hak's is very energetic and has nice playing with a few rough spots. Amph's song has an amazing groove, very clean production and some lovely chords. The guitar also adds a nice touch.
On me vs SuperiorX I went with me because I'm an ass Nah, honestly, I felt my source usage was more balanced between the two songs. Production in Superior's song is clearer and sharper but I have a hard time finding the Sky Road usage, while Metropolis is very evident.
I also loved Sir Nuts' track. Nice production and vibe!
