So Apple not only has iTunes that forces you from now till eternity to use it's hardware for playback, but now they will store the content for you in the Cloud so that you can never actually own it.
If you stop paying for their $20 a year Cloud service, does that mean you will be denied access to the stuff you have already bought?
If so they you have not actually bought the music, you are just renting it.
A perpetual income stream forever and ever.
Here's a really good idea, for about $70 you can buy a 2TB HDD and put about half a million songs on it and never have to pay the Apple Cloud-Tax.
