Change application to be launched using Voice Action Is there a way I can change which app will launch upon Voice action? For example when I say "Listen to Pink Floyd", it currently opens Last.fm app which is more or less useless for me since Last.fm doesn't have streaming in my location. 

Can I configure it to open, say, Winamp instead of Last.fm? If yes, how?
I believe if you uninstall the Last.fm app, then use the Voice Action "Listen to..", a pop up should show asking which of the default players listed here, will show up and be used.

If however, you'd prefer the default in-built player to play, use Listen To or the app Choice Dialer, available in both free and paid versions in the market.
