Well, I'm mighty tired of this genre, but I'd say these guys are in the ballpark of possible success based on what I'm hearing. It's passable Sum182 material.
The drummer sounds very, very good. That's a big start.
Overall, the playing is competent, if not downright good.
The singing drives me crazy, but that's the style. I'd put some 'verb or delay on that lead vocal, but as you say, this isn't a mix, so I don't know what your plans are. Why is it that this genre finds dry, affectation-free snotty vocals so endearing? I hear no soul.
How about some harmony vocals?
The chorus sounds like a prechorus.
I like the fact that there's a bridge.
I would cut the intro in half, and bring in the drums & band after the first time through the chord progression. Get right to the verse. It makes the "one two three four" tough to pull off, but for pity's sake, that's been done so much it's not necessary. (Ask Bono.)
The "Da Da Da" part should be 86ed, and now.
Pretty good job!
