Just DONT try to play Mp3s on a club sound-system, because they DO sound like crap! Mp3s (regardless of the bitrate they are encoded at) usually sound fine on your home system, but can really cause some major shit on a decent rig (some of the side efects of the massive compression used are: loss of dynamic range, harmonic distortion (esp around the 12KHz+ range), degradation of stereo imaging (or complete loss), muddiness around the 40-80Hz range, and basically just a general crappy sound)... which is magnified by the size of the system. I once tried playing a sly Mp3 off CD at a large gig and I had tech-guys tapping me on the shoulder within 30 seconds asking what the hell was up with the music, because it was causing all kinds of weird shit with their VU's & limiters & stuff... I guess the moral of the story is to just go buy the 12" if you like it eh?
