As it is one can not copy the Spotify Storage offline files from one computer or device to another even if both devices use the same account. Every device has to download the same offline files separately.
Allowing the user to transfer or copy the offline cache to another device using the same account would save bandwidth from both the user and Spotify servers. This would be immensely helpful and useful in situations where a user's device is at the end of a very slow internet connection. After downloading the cache once you could copy the same files to your other two Spotify Premium devices with a USB stick, for instance, without having to download several gigabytes of data unnecessarily multiple times.
This would not remove the necessity to validate the Spotify account and the offline files online. But even a slow internet connection can connect to Spotify servers and validate the offline files, even if it would be unfeasible to download several gigabytes over that same connection.
This would also help greatly with mobile devices that often have limited data plans but can still connect to Spotify servers to validate the cache transferred from another device.
