Do you want to have your own mp3 player on your blogs?
I have created a small project using Adobe Flash, there are different files available, one with mp3 file embedded and other supports with external mp3 and both support streaming.
If you are interested you can download the source files here.
Currently there is no support available. And use it at your own risk.
If you are novice to Adobe Flash
Will make a detailed post of how to configure them and change skins etc.
Just post in my comments and will send you mail when detailed post is ready
