Internet music service Spotify announced major new features today that integrate the service with Facebook and Twitter, and help synchronise the service with users' music collections.
The improvements mark an aggressive move against Apple's market-leading iTunes as Spotify aims to attract more users to use, manage and stream its library of music.
Users can now connect to their Facebook account from within Spotify, importing friends, profile details, and browse and share playlists of tracks and top artists with friends. A link also lets users share music choices on Twitter.
The 'Spotify Music Profile' lets users import details of their desktop music library to roganise their music collection, as well as export playlists to sync with Spotify's iPhone, Symbian and Android mobile applications.
The new features will roll out from 9am today and will be available to free and premium users.
Spotify launched in October 2008 and now claims 7m users, though only 320,000 pay the £9.99 annual monthly subscription to access a ad-free, premium version of the service.
The Swedish company, which has an office of 30 people in London, has yet to launch in the US, though it does have a small team in New York.
In comparison, Apple's iTunes holds the credit card details of around 125m users, but Spotify founder Daniel Ek has said that Spotify wants to change the way people consumer music.
"We want to move people from the ownership model to the access model," Ek told the FT.
"We know that this is a huge shift. People are used to owning music – but more and more people are becoming comfortable with accessing music and services in the cloud."
