Spotify's HiFi tier may come with a higher price tag.

Spotify is reportedly planning to release its lossless audio streaming feature, Spotify HiFi, in a new, more expensive subscription tier codenamed "Supremium" later this year, initially in non-US markets. The pricing of Spotify HiFi has been a source of much speculation, especially after competitors Amazon Music and Apple Music started offering lossless streaming as part of their standard plans at no additional charge. Spotify is also considering bundling access to audiobooks into its current Premium tier in the US from October, and potentially sooner in other markets.
