So, after a month, when you've downloaded 10 terabytes worth of music you'd just cancel the subscription. I guess you may have to re-enable it everyone few years to update your collection...

So yeah, I agree, if that were available I'd be the first to sign up and buy my array of hard drives.

I think napster is the most viable existing service that provides a service close to what you are talking about. It has DRM to prevent these types of abuses. It's otherwise affordable. It's not like most people around here don't know how to take DRMed music and rip it...
