Im just a beginner with the whole home recording deal... I have a lot of really close friends who know a ton about this stuff and Ive learned a lot from them but right now I'm recording some music for some people and Ive been noticing that my mix sounds pretty good through itunes and through other programs... through my stereo in my car.. headfones... radio speakers... etc... but immediately as i upload it to myspace for someone the quality just goes down hill... i have no idea what could possibly be the problem.. I'm using Audacity to convert my audio from my PT rig.. but i dont think thats the problem as it sounds good on itunes, CDs, etc...

I'd appreciate the help
