I am trying to download some songs off of someones cd, and everytime i click on one of the songs to download, it says i need more sources....(I dont really know what that means) so i right click on it and clicked find more sources. Sometimes this works an sometimes it does. If it does work and the song begins downloading, once its done it says its corrupted. I dont know what to do. I have only been able to successfully download 5 out of the 16 songs on this persons album. Please help me Thanks
