Spotify adds songwriter and producer credits to iOS
A "Song Credits" feature is being rolled out to Spotify's iOS app, giving users songwriter and producer details of individual songs. The feature has been available on Spotify's desktop application since February. Credits will become available on a song-by-song basis when record labels provide the details. In future, credits could come from publishers, songwriters and societies, said Alfons Karabuda, chairman of the European Composer and Songwriter Alliance.
Spotify first added the option to check out a track’s songwriter and producer credits back in February — and now, the feature is being rolled out onto iOS.

On the desktop application, where the feature was first available, listeners could right-click a track and hit “Show Credits” from the menu to read up on a song’s performers, songwriters, and producers. Now, as spotted by Music Business Worldwide, those listening on the go can access these same credits by hitting the ellipses button that appears next to each song, and clicking on “Song Credits” at the end of the list.

These details aren’t available for every song just yet
