Download songs or videos/movies like apps like Spotify and Netflix

Describe the feature you'd like
I would like to download my songs or movies for on-the-go playback but once I'm online for it to sync any changes as I don't constantly keep streaming my songs or movies every single time I want to consume it. I also like the "encrypted" format as it does seem to save space. In the app it would give you another "tab" for all your downloaded stuff and a choice on mobile data to stream or use downloaded content but should sync every now and then
