From Sony. "Popular streaming websites like Spotify and Pandora typically use a bitrate of 160 kbps, which is less than that of MP3s. If you spring for Spotify Premium, you’ll still only have access to 320 kbps tracks, which is equivalent to MP3s. Tidal is one of the only streaming websites that streams in CD quality. But it still pales in comparison to the emotional experience that High-Resolution Audio delivers." Some other "HD' streaming music sites have resorted to upsampling their files. Just sayin... these days, a consumer seldom knows the "chain of custody" a music file goes through, thus rarely knows how many conversions have taken place.
