MP3 the easy way
Using the Flash Player's built in MP3
support, it would be easy to create a Juke-box application.
If you make sure your users have version 6.0r40 player or
greater, you can even display extra information such as songname, artist, album
etc.
You
can get full details in the release notes for Flash Player 6
.
A cool idea would be to use .NET to create a database of
MP3's providing a search facility etc exposed as a XML Web Service which
could be consumed by Flash.
