Great music, lame coin system

I love this app because I can download popular songs for free and play them on my phone with or without connection but the annoying thing is sometimes it wont let me play songs due to "not enough coins". You have to watch an advertisement while downloading the song which should be enough but now I have to do that and watch tons of ads to get enough coins to just simple play a song. Please get rid of the coin system and then this app will deserve 5 stars.
