I Need Help – Recorder & Editor ~ iSaidWhat?! ~ Share audio to Twitter, Facebook, WiFi, Email, etc. Review

I am not a singer, far from it. ??? But I wanted to make recordings for friends (birthday, anniversary, etc.). When I record a song, it ends up with a black square in the middle. Is there a way to have your singing/talking overlay a video? Example, if I make a movie in Windows Movie Maker, do I just insert the recording as the background track? Or is there a way to add pictures, video clips in this app? Thanks for any help! Why aren't there any instructions from developer? ???
