Use S-Voice with different music player?

Is there any way to have S-Voice start a different music player (e.g. WinAmp)? Google Voice Search Now Thingy (I never know what to call that) seems to use the standard app launching mechanism where it shows you the "pick an app ... Always/JustOnce" dialog, but when I say "Listen to <song>", S-Voice just launches the stock music player.

Switching to Google Voice Search Now Thingy isn't really an option for me, because it does a really poor job of handling the names I need to to text and call every day, whereas S-Voice does a great job.
