A Spotify app is now available to download to your games console, or you can use one of Sony's Xperia devices to link your Spotify and PlayStation Network accounts.
If you used to subscribe to Sony's now defunct Music Unlimited service, you can take advantage of a 60 day free trial of Spotify Premium. New and existing Spotify users can get one month free (as long as you've never had a free Spotify trial before).

PlayStation Music will launch in 41 territories and will allow PlayStation Network's (PSN) 64 million users to link their accounts with Spotify - and have the option of signing up to a Premium subscription through the PSN wallet.
Sony's Music Unlimited service will close on March 29th 2015, which Sony says is prior to the launch of PlayStation Music, could it be it will arrive on March 30th? We can't say for sure.
Gamers who link their Spotify accounts will be able to access songs and playlists from within games, and use the music as a soundtrack. But this will only be available on the PS4 and not the PS3. Users will also be able to create collections and playlists, and access playlists curated by other Spotify users.
