I purchased 2 songs from Amazon MP3 and when I go to the music app the 2 songs plus the 5 songs that were pre-installed show up. When I am at the home screen and go to the screen to the right that originally had the 5 songs on it I thought it would retain the 5 and add the 2 I purchased. Instead it only shows 1 song. I know it can't be this difficult. ?????????
