If you used the simple song collector to gather songs on the Galaxy, then all the songs should be visible in the Android file manager in a folder called simplesongfinder that is a subfolder of the downloads folder. Email those to your wife maybe 5 at a time. Open the email on the iPhone, tap to open each song file, find and tap the share button, pick walkout song dj to import and pick 'song or sound effect' when asked. That will put the song in the imported file folder of the Walkout Song DJ app. If you have already shared and imported the data file from the Galaxy, then it should match up the players to the songs automatically.
