Follow along with the video below to see how to install our site as a web app on your home screen.
Note: This feature may not be available in some browsers.
First create a "scene" in tasker. Add the image that you want, and play around with the size until it looks right. Click on the image after you've added it, under "on tap" add an action to "destroy scene" and another action "music stop"
Add a Tasker widget to your home screen, add a new task when asked. First action should be "show scene" and add the name of the scene you just created before this (use "dialog" from the drop down list, that seems to be the only one that works for me). Next action, "music play" and add the file of the song you'd like to play.
And that's it. You can add an icon to the shortcut if you like.
