The main purpose of the digital certificate is to ensure that the application belongs to the entity to which the certificate was issued. The Spotify Ltd digital certificate does not guarantee that a signed application is safe to run, but rather informs the user that the software was digitally signed by Spotify Ltd and verified by a trusted Certificate Authority (CA).

Spotify is a Swedish music streaming service offering digitally restricted streaming of selected music from a range of major and independent record labels, including Sony, EMI, Warner Music Group and Universal. Music can be browsed by artist, album, record label, genre or playlist as well as by direct searches. On desktop clients, a link allows the listener to purchase selected material via partner retailers. A six month free trial period is activated upon Spotify account registration or first login with a Facebook account, where a user can listen to an unlimited amount of music supported by visual and radio-style advertising. Users can access applications integrated in the Spotify desktop client, written in HTML5. Third party software writers can offer features related to music listening such as live sharing of playlists, music reviews, lyrics, concerts.

Spotify principally operates under a so-called 'freemium' model, which is offering simple and basic services free for the user to try and more advanced or additional features at a premium offer; however this is augmented by income from music purchases within the player. It offers a US$10 per month unlimited subscription, close to the Open Music Model (OMM) estimated economic equilibrium for the recording industry. However, the incorporation of DRM diverges from the OMM, as well as from competitors such as iTunes and Amazon MP3, which have dropped DRM. www.spotify.com
