Want to give props to Barry for doing a bang up job with his mastering. He took a pretty raw, slightly mushy, muddy track with a less than optimal mix, some phasing issues and pretty poor stereo positioning (I'm a pretty lazy producer, and rely on mastering engineers being good at their job) and Barry has made it tighter, punchier, louder and generally made it shine.

The track he mastered for me is on my soundcloud here:
Jay Pace - Jay Pace - Murda Mile (Free Download) - SoundCloud

I'd recommend downloading the full WAV file, soundcloud's 128kb player version won't do it justice.

Excellent work mate. Bravo.
