PlayBackgroundMusic gives ContentLoadException on Windows Phone 8

I've loaded up an MP3 in my project via the Content/sounds folder, set as Build Action = Content, do not copy.
 CCSimpleAudioEngine.SharedEngine.PlayBackgroundMusic("sounds\\theme.mp3", true);
This line throws a ContentLoadException with "failed to load content"

The mp3 is in the same folder as two WAVs that I've already processed as XNBs (click.xnb and gameover.xnb)

These lines right above that line:
...execute just fine.

Am I missing a step to prepare the MP3 to be loaded?

Can you dig out the inner exception on the ContentLoad exception? MonoGame throws a standard ContentLoad exception and passes along the inner exception. That inner exception is important as it will tell you why the content is not loading.

Unfortunately, the innerexception is null.

Here's the full detail:

Nevermind, I figured it out. Didn't realize I needed the raw file AND the xnb for the MP3.
