Music streaming service Spotify asked a range of leading artists to create apps to help "categorise and organise" its 18m-plus music tracks, as well as "educate" fans on genres and subgenres.
Among the first artist apps is Quincy Jones: The Stories Behind the Music, offering exclusive audio interviews with Jones, as well as tailored playlists and artwork.
The producer of numerous hit albums, most notably Michael Jackson's Thriller, will discuss his own personal heroes and mentors, along with the art of hit-making, and how his music is used in the movies.
At a launch event in Los Angeles, Jones joined the singer Bruno Mars to discuss the Spotify app and his incredible career in music.
"The Spotify Artist App is a wonderful opportunity to share some of the behind-the-scenes stories of a few of the memorable recordings that I have been fortunate enough to make," he said.
"I think this App will give entertaining insight and value for these recordings to both music fans and aficionados."
Superstar DJ Tiësto has also created a Spotify app, called Club Life, that will curate the best dance music across Spotify, with features such as 'Single of the Week', 'Album of the Month', 'Festival of the Month' and a chart of the hottest dance tracks around.
"Spotify is one of the most exciting platforms out there, helping to redefine the way people listen to music," he said.
"I'm delighted to be part of it, and to give dance music fans a new way to discover artists, albums, festivals, and to share what I'm into."
Rancid will use their app to show that punk still bears heavy influence over music. Every week the band's Tim Armstrong will present a new playlist of tracks "taking fans on a trip into his personal record room to take a deep dive into the music that inspires him".
"I always want to share music with my friends and tell people about artists... both new and old," said Armstrong.
"Nothing is more gratifying to me than turning people on to music and making it a part of their lives and then, them in turn, turning it onto other people. There is nothing like having music in common. We are truly looking forward to this whole thing."
The Disturbed app will feature playlists of past, present and future rock and metal music compiled by each of the band members, along with special guests.
Artist apps are available to users worldwide on the Spotify desktop client via the left hand navigation bar. There is also an App Finder tool for discovering new services.
Spotify said that a number of other artist and music expert apps will launch in the coming weeks, including one from American electro house DJ Steve Aoki.
D.A. Wallach, the American songwriter and Spotify's artist-in-residence, said that the goal is to "partner with artists to create the best possible experience for our users".
"With these new apps we wanted to create a space on Spotify where artists could have 100% creative control - giving the apps their own feel, functionality and direction, and building rich and engaging experiences for their fans," Wallach added.
