I don't think clipping and intonation were any big whoop.
I know the original version, so I can't help comparing.
The original had a lot more 'pop' and 'edge' in the attack of the instrumentals and vocal; that is, the unison figures were aggressively struck, and the sustain was cut shorter. What you end up with by not doing that is a lazier roll-along...which may be exactly what you want...but isn't as impressive and pleasing as the original hit version. The tightness and dynamics of your version are less. Maybe a couple gallons of coffee for the fellers before the session would have kicked it? :^)
Thing #2: the panning.
You have a big fat ball of midrange instruments droning in the middle field ...which hurts the impact of the vocal. It's stereo, but the sum of the panning gives it a mono stain. I'd suggest moving droners to the flanks, leaving the middle for vox, feature guits, bass, and snare and bass drum.
The vocal could use some tweaking to even out some of the words, tails and decays... volume enveloping....
There's something about the finished product that makes it sound overall over-compressed. That might be MySpace's thing....or you compressed it to death to make it sound 'radio'. Realism and presence is lacking. Could be the big ball of mids in the middle, too.
The high point is the sound and pan of the background vox. They're coming through real nice. A nice tight vocal unit...just like it says in the blurb. And the guys play good....just need to whip up a little more attention to dynamic and figure detail to add some tooth to the grind. And the music's appeal would improve, I think, if the parts were thinned a bit. Mass droning sounds good, but in smaller doses...need a little space.
Do you record your own stuff?
