Spotify has added a host of new applications to its desktop client, including the innovative Now That's What I Call Music! based on the best-selling compilation album franchise.

That specific bright and colourful app adds playlist generation, the UK charts (in our region) and all manner of fun tomfoolery based around pop music. But it's only one of many interesting additions to the platform.

Thirteen new apps have been added in total, from record labels and distributors including Universal, Sony, Warner, EMI, Def Jam, Domino, Matador, PIAS and X5. There is Classify for classical music lovers, Def Jam, which offers - as well as immediate access to music from the illustrious hip-hop/R&B label's vast back catalogue - history and information about its artists, and Filtr, which adds a social element to playlist creation by scanning selected Facebook friends, among other things.

"These Spotify Apps offer something for everyone, from ways to discover music both old and new, to amazing imagery and apps simply there to entertain," said Sten Garmark, Spotify's director of Platform.

"The potential for Spotify Apps is just massive and we can’t wait to see what people are going to blow us away with next."

Here's the full list of new apps (with Spotify's own explanation for each):

Classify: Classify opens Spotify’s doors to the world of classical music. Browse by composers, eras, moods, instruments or genres. A vast library of classical music is now intelligently organised for your listening pleasure.

Domino: The Domino Spotify app is a discovery and listening destination for fans of Domino artists, the Domino label and the larger independent music community. Through the app, Domino leads the listener through its 20-year history by highlighting artist playlists, custom catalogue exclusives and commentary from their friends and neighbours in the world of indie.

Filtr: Filtr is a playlist app, which allows you to build playlists based on the music tastes of your Facebook friends, people who’ve accepted invitations to Facebook events, music genres, your Spotify playlists and favourite artists. On top of generating awesome playlists, Filtr also recommends existing and live updated editorial playlists based on what you like.

Hot or Not: Hot or not? You decide. Cast your vote on one of the two songs in the battle, either based on what you think is the most popular or what you wish to make popular. You’ll be rewarded with points and can earn badges as well as track your progress. Your voting will also contribute to the "Taste Maker" top list based on users with the highest points score.

The Legacy Of: A visual feast. Dig deeper into some of the world’s most acclaimed artists with hi-res photos, curated playlists, handpicked albums, biographies and more.  Delve into the catalogue of artists like Bob Dylan, Miles Davis, Daryl Hall & John Oates and Stevie Ray Vaughan.
