I will soon start uploading some of my songs to the web. I have created a Soundclick, and Soundcloud account. These are some web site that stream audio from the web so that you don't have to download anything.
My clients now have a space where they are comfortable tracking their material and know that the music they produce will sound as good on other systems as it does in my project studio. Now I can concentrate on making great beats and tracks rather than trying to process the sound based on misinformation that the room was creating before.
I will keep you all posted.
