Amazon today announced the immediate availability of Amazon Music HD, which delivers millions of songs in Ultra High Definition, the highest quality streaming audio available.

“We spoke with many artists while developing Amazon Music HD, who were excited about the potential for fans to be able to stream their favorite music, and hear it as it was originally recorded,” Amazon VP Steve Boom said in a prepared statement. “From rock to hip-hop to classical and pop, we believe listening to music at this level of sound will make customers fall in love again with their favorite music and artists. As we usher in a new listening experience for our customers and the industry, we’re combining the convenience of streaming with all of the emotion, power, clarity, and nuance of the original recordings.”

Amazon Music HD is available in the US, UK, Germany, and Japan for $5 more per month than the firm’s individual and family plans for Amazon Music: That’s $12.99 per month for Amazon Prime subscribers and $14.99 per month for everyone else. The service provides over 50 million songs in High Definition (16-bit, 44.1 kHz; essentially CD quality) and some millions of songs in Ultra High Definition, a lossless format (24-bit, up to 192 kHz). Amazon says that subscribers will always stream the highest-quality version of any song they listen to.

The service has one important backer, artist Neil Young, who has been promoting lossless music for years while decrying the quality of most music services.

“Earth will be changed forever when Amazon introduces high-quality streaming to the masses,” he said. “This will be the biggest thing to happen in music since the introduction of digital audio 40 years ago.”

Amazon Music HD is compatible with PC, Mac, Android, iOS, select Amazon Echo devices, Fire TV, and Fire Tablets. Amazon says the service is also compatible with many third-party devices, including most products from Denon and Marantz with HEOS Built-in, Polk Audio, Definitive Technology, Sonos, McIntosh, Sennheiser, and many more.

New users and existing Amazon Music subscribers can try Amazon Music HD for free for 90 days. You can learn more about Amazon Music HD at the Amazon website.
