Apple should offer a 'all you can eat' streaming subscription service on iTunes

I think it would be great if Apple offered a 'all you can eat' subscription service on iTunes. Basically you would pay a set amount per month (£20, £25?) and you would have access to all the content on iTunes (apart from the App Store).

The service would ideally work in a similar fashion to Spotify, where content is streamed directly from the server, rather than downloading the content to your computer (but like Spotify, you would be able to save 'Offline Playlists' to your devices, so you can access them while offline).

A streaming service means that users would not have to worry about large HD video files taking up loads of hard disk space, which is becoming a problem for some users.

This kind of service would work great when paired up with a AppleTV. Imagine having all that content from iTunes, all available to watch anytime you want, for just £25 a month? I'm sure a lot of people would ditch their Sky/Cable TV subscription for something like this!
