That sounds like an issue with the Android media manager database. You can verify the songs are actually downloaded by opening your Android file manager and looking in the Download folder and then the SimpleSongFinder sub-folder. If they are in there and still not showing up in the My Music folder of Walkout Songs, then that confirms the issue is with the Android media manager. Usually power cycling the Android device will reindex the Media Manager database and fix the problem. If they still don't show up, you should be able to pick the browse option from the Walkout song picker and just manually pick the songs from that download folder.
