Spotify wants to suggest music based on your mood.
The music streaming service is planning to launch new patented technology that will analyze users voice to track their emotions and environment to play tracks that are best suited to their "emotional state, gender, age, or accent".
Spotify explained: "It is common for a media streaming application to include features that provide personalized media recommendations to a user.
"It should be understood that the above example metadata categories of emotions, gender, age and accent are merely examples, and numerous other characterizations and classifications can be used."
The technology will combine the data with other information, including a user's previously-played songs, and their friends' taste in music to choose what music to play.
It comes after the streaming service recently launched the new Listen Alike feature for music lovers who have ever thought about what their favourite celebrities and musicians are listening to and how it compares to their own taste.
In December last year, Spotify became available on the Epic Games Store.
The music streaming platform has launched on the online games marketplace - originally intended as competition to Valve's Steam - and can be accessed with a free download.
The blurb on the page reads: "Love music? Play your favourite songs and albums free on Windows with Spotify.
"Stream the tracks you love instantly, browse the charts or fire up readymade playlists in every genre and mood. Radio plays you great song after great song, based on your music taste.
"Discover new music too, with awesome playlists built just for you.
"Stream Spotify free, with occasional ads, or go Premium."
Epic Games added on Twitter: "Spotify is now available on the Epic Games Store! Discover new music and podcasts while you game.
"Listen to the songs you love and enjoy music from all over the world."
Spotify is the first non-video game app to be offered on the store, and it seems to suggest that Epic is looking to expand its digital marketplace.
CEO Tim Sweeney teased: "The Epic Games Store now stores more than games!"
