I'm a premium user but I'm frustrated with one thing. Could you manage an option to randomize all the songs of all the playlists? I have a playlist for each artist I like but would like to mix all these artists without going back to the app on my ipad each time I want to change. I would prefer a randomizing option for all my songs. I'm sure it's not so tricky to do so and I've read many users online asking for it. Thanks.
