To delete a playlist, go on my.meural.com and click on the User icon in the top right hand corner of the screen, it looks like a person in a circle. Next, click on Canvases in the drop down menu. On the next screen click on playlists at the top right hand corner. On the following page you will see all of your playlists and they will have an "x" in the right hand corner when you roll your mouse over the playlist you want to delete. Click on the "x" and this will remove the playlist from the Canvas, but not from your list of playlists from my.meural.com.
