Update: Can't purchase music at all anymore. Original: I agree with other reviews that the interface is clunky. Why does the "buy song" option lead you back to the Amazon Shopping page? It doesn't even take you to the song you are trying to purchase. You have to search for the song all over again. I don't understand why the developers thought this was better than buying the song through the app. Several updates later and this still has not been addressed. What gives?
