Xpo Music provides you a great Spotify music experience with beautiful look.
Besides good looking, there are plenty of features which absolutely impress you as well as it does to me. If you jump into its settings you will see a tiny pop-up windows inside it.
Dark theme is now ridiculously on trending -- you've probably known that, right?, even in Facebook, and this theme is also featured in this opensource Windows app. It allows you to preferably change theme between light and dark. Next, more are Live tile preference, Interface languages and Cortana integration. It means every music image tile will be loading lively; you are able to change its language to your native one or whichever you prefer and use your Windows's Cortana to voice-command on it.
If you are a Spotify user, Xpo Music app is a great app you can try. It supports both free user and premium user of Spotify.
