They also bred gene-edited chickens intended to serve as potential surrogates for the dodo and other ancient bird

If you listen to music the way a lot of people do these days — with a pair of wireless earbuds, from a Bluetooth speaker, or just blaring directly out of your phone — you will never notice a difference between Spotify’s high-quality 320Kbps streams and its lossless audio. But, if you usually listen with wired headphones while working at your desk, or have a quality speaker from the likes of Bose that supports Spotify Connect, there actually is something to be gained here.

It’s been a long time coming but Spotify is finally getting lossless audio. Rumors have been circulating about a high-fidelity offering since as early as 2017. In 2021, Spotify claimed it was “coming later this year.” And by May of 2024 it was “almost ready.” So, when rumors started picking up again in June of this year, they were met with skepticism, especially amid announcements over the launch of features nobody was asking for, like direct messaging.

Decades-Old Waste Barrels Are Creating Toxic Dead Zones off LA’s Coast

Until 1972, the Pacific waters of Southern California served as a dumping ground for hazardous and industrial wastes.
