Amazon wasn't immediately available for comment, but MWB reported the rumor from "several high-placed music industry sources." Those sources said Amazon's hi-def service would cost about $15 per month and launch before the end of the year. The price would be cheaper than TIDAL and Deezer's subscriptions, which cost $19.99 per month. Additionally, Spotify and Apple don't have high definition streaming options.

"It's a better bit rate, better than CD quality," an unnamed source told MWB. "Amazon is working on it as we speak: they're currently scoping out how much catalog they can get from everyone and how they'll ingest it."
