I downloaded the app around 8 months ago with the "1$ per month first three months" offer for the premium version. Had it since then, and it's absolutely great. You can download songs to your phone and play them with data turned off, you can use your phone as a remote for the ps4 app while you have a game running, and you can choose from a massive library to add to your own collection. It's worth the price for me. The account integration is pretty sweet too. I can basically use my phone as a Spotify ID and take control of any smart device that has the app.
