Flash based player with playlist loaded with all their music (it will be connected through mSQL database)
Make it embed
Add a section on the dashboard for each user so that they can copy and paste the code on other websites (for example on Facebook or their own website)
A button by every song labeled "Buy Now" that takes them to that individual music file's page
Styled so it is unformed with my site's theme
Player displays user's avatar.. I only have mp3 files, and it has to be compatibly different versions of firefox, IE, safari, chrome. I want it to be able to be shared on Facebook and other sites like blogs, and other pages.
