Designed with ease-of-use in mind, this app's interface is fairly comfy. From your main screen you'll notice that all of the channels available are listed so you won't need to scroll up and down in order to change stations. Plus from your settings menu, there is a customizable list of channels that you can toggle through. Say you'd like to listen to the latest one hit wonder -- there's a channel for that. While it isn't included by default, all you have to do is add it onto your channel list to listen.
Stations by Spotify is an excellent alternative to Spotify's official app. Particularly for users who aren't interested in paying for 'Premium' user status. Enjoy thousands of top hits without the hassle of finding them. Plus it's ad-free and won't cost you a cent.
Android 4.0.3 or higher required.
