I consider reliability to be a fundamental element of access. If I have music on my hardware, I can always play it. If other people are granting me access to download music from their hardware, I can play it whenever I have access to their hardware, up to the limits of whatever constraints they have chosen to apply to their service, which may include having to spend money or listen to ads.<p>Different people have different needs; I&#x27;d rather have a smaller collection of music I can count on than access to all the music which is encrusted with hassle and advertising.
