I must say that this is an awesome app for the regular Soundcloud user. I currently use this app on an android phone and it works great. You can esaily convert your phone into the ultimate juke box with original music from thousands of Soundcloud artists.
The app allows you to do many things including leaving comments, reading comments, following new talent and checking artists play stats. If you are serious about your sound cloud music, definitely download this app and keep the music going at home and on the road.
