Will Not Save Playlists for Offline mode. Can not save to SD card.

[BuCKetZovBlOoD]

I Have This Issue For Awhile Now Where Every Few Days My Playlists Will No Longer Be Available Offline.  I Have To Re-Download Hudreds Of Songs Every Few Days. Gets Frustrating After Awhile. I check my SD Card And Everything Is Working There. Also After The Last Update I Have Not Been Able To Save To My SD Card. It Will Download A Few Songs And Stop. Ive Deleted Cache And Saved Data And It Will Still Do The Same Thing. I Un-Installed The App And That Didnt Help. Please Help This Is Frustrating As I Listen To My Playlists Offline At Work Because I Dont Get Phone Service In Certain Areas. Now Im MUSICLESS!!!!!
