How do I listen to songs that's downloaded?
 

Yesterday I wasted my whole day downloading a whole bunch of songs and now, there's no way I can listen to them! Any one know what I'm suppose to do? And All of the songs were finish downloading but for some reason it ended up in the "incomplete" folder. Can you also tell me what's up with the playlist? Can I actually save the whole playlist after I add the songs to the playlist or do I need to save them one by one so I can listen to them. Please help me. I don't want to waste the whole day downloading everything all over again. Thanks
