For media files like Music, I keep them on Windows desktop which gets synched to OneDrive 1TB account which came included with MS office subscription which I need anyway that is only $10/mo for both app and storage which sounds like a steal against other cloud storages.
Ah yes, I forgot to mention that I use OneDrive for an additional backup of photos - I have an MS Action Pack subscription, which gives me something like 5TB of storage (I forget exactly how much, but it's a lot!)
