The service is coming to both PlayStation 3 and 4, and it's thanks to Spotify's established licensing deals that the service will be available in way more places than Sony's offering could (41 for Spotify, 19 for Sony). As per regular Spotify, the ad-supported version is free, or you can cough up $10 a month to listen without interruption. There is a free trial for newcomers, and if you were previously paying for Music Unlimited, then this is extended to 60 days. If you were worrying about being able to pick individual songs while playing games (rather than playlists etc. as is the case on some platforms), the good news is you can.
