SD Card suggestion

Hi,

is there any future update about having an option in deleting playlists from the SD Card or deleting Playlist and tracks from the SD Card "All Tracks" collection, since there's users use playlists with same tracks in the "All Tracks".

Example, i'd like to delete my playlist and the songs inside it from the "All Tracks" in my SD Card at once, no need to search for these songs as my songs are so many in the "All Tracks".

Thank you
