When I play a public playlist, and then move around the app, I can't find the playlist it is from. If I click the Album art it takes me to the "Mood" page from "Browse > Mood". It is really frustrating when I have been listening to a playlist I like and can't return.
Update: This should have been fixed by now. Clicking on the album art should get you to the public playlist now. ;)
