Led Zeppelin's entire catalogue is available on Spotify from today (December 11).
In a press conference, the music streaming site's founder and CEO Daniel Ek announced that the band's music will now be available to listen to for free on the service.
He also announced that Spotify will now be available for free on any platform – including mobiles and tablets. Spotify had previously required people to be paying subscribers to use its smartphone and tablet apps, with its free service restricted to desktop use only.
The move is seen as a response to competition from Apple's iTunes Radio, which is so far only available in the US.
"Today we’re giving people the best free music experience in the history of the smartphone and the tablet," Ek said in a statement. "Whether you're going to the gym, or having a party with friends. Just sit back and let Spotify serve you great music for every moment of your life."
Last week (December 3), Spotify announced a new website for artists, which will explain how its business model works and publish figures on how much musicians can expect to earn as the company grows.
It follows criticism from artists such as Thom Yorke, Foals and David Byrne, who spoke out against what they say are low royalty rates paid to artists who use the service.
Major artists still yet to sign up to Spotify include The Beatles and AC/DC.
