Here are some tips I picked up from another thread. The first one was left by some obnoxious nutwing, and I quote:

"Go to iTunes... Open preferences in the EDIT menu... Click the GENERAL tab... Under "Internet" go to: Use iTunes for internet music playback... Click on SET... Click OK to exit..... DONE!!!!"

Believe it or not that one worked for me.
Here's the other:

"Go to the Apple Menu and select Control Panels. See if you see anything called File Exchange. If you do, open that. You'll see a window where you can choose which application opens which type of files. Scroll down to mp3 (or hit the M key to get there much quicker). Highlight the application, and select your preferred player."

This one I'm not too sure about but if it helps anyone, what the heck. See Ya!
