Using Bluetooth headphones to control Winamp Pro on Android?

[funkinlesson]

Hi,

I have a Samsung Galaxy S3 that's running Android 4.0.4. I have a set of Sony DR-BT101 Bluetooth headphones that have controls on them for skipping tracks etc.

I installed Winamp Pro but when I press any of the headphone controls it launches the stock music app. How can I get the headphone controls to control Winamp Pro instead?

Thanks.
