“indefinitely” is a huge loophole, not a lifetime guarantee. If that word was used by Google at the time, there is no case here.

YouTube music is shutting down the lifetime guarantee is for the product or service life not the subscriber's life. So I am not sure where they are wrong in shutting the service.

whether or not this could be called a lifetime guarantee was not the point of my comment, at all.

typically, purchasing something with a lifetime guarantee requires an up-front payment to secure the lifetime guarantee. it seemed like some people here might have been under the assumption that was the situation with google music. i just wanted to make it clear what the actual situation is.
