Streaming HD music from Amazon? It just became a thing.  Free trial  now available.

Of course there are many questions. Will Tidal survive this? How about Qobuz? How does it affect "boutique" hi-res lables? Will this raise the profile of HD music in general? Does Amazon have hardware on the way that focuses on fidelity?

One thing I know for sure is I'm signing up for the trial today and with Amazon in the game, HD music streaming just got its largest-ever platform. Will Apple make its move next?
