EDIT: The only reason why I still had it at this point was because I could use it with other apps. However, now that my Spotify Subscription is cancelled, it doesn't work with anything. It's mildly infuriating because today, I can't still use it with other apps like I was able to yesterday.
Please don't make the same mistake I made. No one should buy this.
All it provides is a simplified ui and voice control, the same voice control as the Spotify app. It doesn’t even play the audio, it is a remote for the app on your phone which is doing the real work.
