5 stars: I will never listen to music on youtube again. this has 100x less ads,and you can save music to listen to offline FOR FREE, which is something you can only do on youtube with premium. also, you can listen while your phone is off. this is a lot better for me because my phone is quite old and the battery goes down very fast. it takes up very little space and loads quickly. if you want an app to listen to music with, this is the right choice.
2 stars: SoundCloud is generally great, but nothing more frustrating than refusing to stream a set (for unknown reasons) you've had your eyes on. Icing on cake? After being forced to add it to a playlist to try and download it, the app asks me to give it a rating. Hmm. Typically both a great app and service, disappointed by this behavior.
