Presumably in celebration of PlayStation Music's one-year anniversary, Spotify--which powers the service--is offering a pretty sweet deal on its Premium subscription package.

New and existing Spotify members can now get three months of Premium for just 99 cents. The one catch, and it's a big one, is that the offer is only available to people who have not previously gotten a trial of Spotify Premium.

You can grab the deal here--you must redeemed by June 30. Official terms and conditions for the offer can be seen here. Premium normally goes for $10/month.
PlayStation Music is available on PlayStation 4, PlayStation 3, and other Sony devices. A Premium Spotify membership gets you extras like offline play and no ads. You can also listen to tracks while gaming, which is proving popular, as people streamed 5 billion songs through PlayStation Music in its first year.

In a post on the PlayStation Blog, PlayStation senior marketing manager Carrie Surtees said PlayStation Music has been a massive hit on PSN.

"Thanks to you, Spotify has become one of the most downloaded apps in PlayStation history, and together we’ve reached more than five billion streams," Surtees said. "Now, we're excited to introduce our music-loving players to another level of listening."

Background music support is also coming to Xbox One through a future update, though it remains to be seen if this will be done through a partnership with Spotify or by leveraging Microsoft's own Groove service. For its part,Sony has said Spotify may not be exclusive to PlayStation forever.
