I cannot dispute Scoredaddy's results, as he seems to know what he is doing, and I have no way to either replicate or negate his results. Yet, I will defend the Amazon HD service as (at worst) incompetent, or (at best) buggy. I do not believe they are trying to defraud the users. I just think the service is not yet free of bugs, has very erratic metadata, the bit rate jumping still happens to me mid-song, albums with tracks that don't belong to it or have UHD and HD tracks mixed together (as Amazon defines them in the context of their HD service). The service is far from being ready-for-prime-time. It may never be bug free before Amazon gives up on it. But I do not believe they are trying to defraud us on purpose. That is why they gave out the generous 3 month free trial, we are the beta-testers. It is up to each of us as informed consumers to decide when to opt in or opt out of the service, to pay or not to pay, knowing how the service works or doesn't work for you. I have until Jan 11 to decide.
