How to record your song and put it on iTunes?

So, how do you record a song on your iPad or iPhone and put it on iTunes and somehow make a music video with the song? VideoStar works, any apps that you can use on the iPhone is good. Any answers are very much appreciated

To record you can use the sound recorder on your iDevice. To pt it on iTunes you can backup your iPhone. It will ask you if you want to back up your recordings. Then once you get to the backup file cut it and add it to automaticly add to windows.
