Exhibit A: Aforementioned low-end problems. The bass sounds like it was recorded through a guitar amp. Also the "easy for me to say" bits were weak. Guitar solo bit is too indistinct. The drum roll is sloppy, sounds like the snares are too loose just on that part. Otherwise great snare sound.
Exhibit B: WTF intro. Much better low end. Panning is a bit distracting through headphones, but maybe through speakers wouldn't be so bad. I absolutely love this snare sound, btw. Cymbals are better in this one, too. Bass is still too thin. "Easy for me to say" is still weak. Guitar solos are much better, more up front, and seperated. Kick is a bit cardboardy though.
New mix thingy: Great mix, the kick and bass sound better balanced.
Overall, really great song, and your newest mix, definitely the best.
