Show Menu of Music Apps when Headset Inserted

Here is how to have Tasker detect your headphones and launch a menu of Apps to choose from instead of just the default music App.

• Click "New" name it "Headset" and click "State" 
• Select the category "Headset Plugged" and leave the type set to "Any"
• Click "New Task" name it "App Menu"
• Click the "Add" button in the bottom left and select "App" and "Load App" Choose a program such as "Music Player" then click "Done"
• Click on the "Settings" (Spanner) Icon and change the "Task Type" to "Menu" click "Done"
• Click "Add" again and go to "App" and choose "Load App" again and choose your next App such as "FM Radio" then click "Done" again
• Repeat this for as many apps as you want to be displayed.
• Click "Done"

Now whenever you plug in your headset you will be presented with a list of applications to launch. I have Music Player, Google Listen (for Podcasts) and FM Radio set up on mine.
