Would be awesome to have an option to automatically download the latest 20 or so songs on a playlist. I usually put all my songs on the same list that is now many hundreds songs long. So downloading it for offline use is not an option since my phone doesnt have infinite amount of harddisk space. So an option to only download the latest songs would be nice. For example 20. So when you add a new song the app would download the new song and when "forget" or "un-download" song number 21.
