This is about the FOURTH TIIME in the past month that my offline status has been removed from a nearly 3,000-track playlist with no intentional (or observed) intervention from me.  Furthermore, each time this occurs, my default storage location is changed from my SD card (to which I have explicitly set it several times) to my "Device Storage" (my S4 device's own, much smaller, internal "SD card," which does NOT have sufficient space to store the tracks on this playlist offline.

Furthermore, once I tapped on the SD card in STORAGE and it started transferring, when I tap again at first, it says "transferring," as it should, but then a few minutes later I tap on SD card again and it acts as though this is the first time I am requesting this, asking me to confirm the transfer AGAIN.

So this is buggy, not just inconvenient.

It has been pointed out repeatedly by myself and others that at the very least confirmation should be requested before taking a playlist that is offline ON line again, and deleting all of the downloaded tracks.  And yet nothing has been done.  And now it seems that no matter how careful one is, this occurs again and again.

So when will Spotify take this absurdly simple measure?

Other than the above, love the service and practically everything about it.
