Amazon Music HD Unlimited users also have an additional incentive to stay with the subscription music service: Amazon has also made the Amazon Music HD streaming tier accessible for all current Amazon Music Unlimited subscribers.
The announcement came on the same day as Apple revealed that Dolby Atmos and lossless audio would be available for free on Apple Music.
New and current Amazon Music Unlimited Individual Plan ($8 a month for Prime members and $10 a month for Amazon customers) and Family Plan ($15 per month) users will now switch to Amazon Music HD for free.
Amazon Music HD has over 70 million lossless, CD-quality tracks with a bit depth of 16 bits and a sampling rate of 44.1kHz in its library.
There are, however, over 7 million tracks licensed in higher-than-CD-quality hi-res audio with a bit depth of 24 bits and a sampling rate of up to 192 kHz. Since its initial release in 2019, Amazon Music HD has introduced over 5 million tracks to its high-resolution library. According to Amazon, this is the biggest collection of high-resolution music online.
Amazon Music now offers an increasing number of tracks in 3D Audio platforms such as Dolby Atmos and Sony 360 Reality Audio. Dolby Atmos tracks will currently only be streamed on Amazon’s own Echo Studio smart speaker. Meanwhile, Sony 360RA tracks will be compatible with Sony’s RA5000 and RA3000 speakers through Alexa Cast.
Previously, the Amazon Music tier was an extra $5 a month for new Individual or Family Plan users. Present Amazon Music HD customers would not be charged an additional fee for HD beginning with their next billing period.
