I've gotten SmartActions to see playlists when I install the app "Hi Music".
I still have a problem though, when the action is triggered, it only plays the same artist every time, it doesn't open up the playlist I have selected.
I was wondering if I take the songs out of their artist subfolders if that'd make a difference... I'll get back to you guys if that works, just have to find the free time to do that. Let me know if you guys get to it first!
