LOL - if your mixes sounded good, then they would sound good in MP3. If you are that insecure about your mixes translating to another format, then you need to not boast... Double check them on a stereo, dude. In case you haven't noticed, end users don't listen to music on monitors straight off 2" tape. =oP
Sorry guys... I just wanted to add one post to this. It's kinda like a game of Jenga!
