Swedish music-streaming service Spotify celebrates its first birthday today.
The music-streaming service allows users to create a playlist of songs they want to hear from Spotify's catalogue. They can also create 'collaborative' playlists, which are assigned their own web addresses, and can then be added to by other Spotify listeners.
The tracks are broadcast in a style similar to commercial radio, in that they are peppered with adverts.
However, for 99p, Spotify users can purchase a whole day of ad-free listening, or alternatively pay a £10 monthly subscription and never hear an advert again.
Spotify was originally 'invitation-only' when it launched in the UK a year ago, however in February this year, spotify removed the restriction in the UK, only to reinstate it again in September, following a surge in popularity after apps for Apple's iPhone and Google Android handsets were launched.
Despite being loved by web users, Spotify is causing a headache for IT managers, especially when it comes to bandwidth.
"At the moment, when it comes to knowing what data is travelling over their network, businesses are stumbling around in the dark. They can see that there is congestion on the network, but not what's causing it. It's just like being stuck in a traffic jam on the M25," said John Cunningham, director of business markets, ntl:Telewest Business.
"Organisations should consider implementing fair usage policies for social media technologies that take into account how they support the business, whilst ensuring that vital applications and systems aren't impacted. As the industry moves towards a more proactive model of network management, service providers will be unable to ignore the need for increased transparency."
