Amazon Music offers a wide variety of music formats. In addition to standard definition (SD) audio, some tracks in the Amazon Music catalog are available in high-definition (HD) and ultra-high-definition (UHD) lossless formats. Amazon Music even offers spatial audio in Dolby Atmos and Sony 360 RA formats. Please note that not every audio track is available in all formats.
Only standard definition (SD) is available for the Free and Prime subscription tiers.
