I'm making a video (bunch of pictures with music in background) for my cousin because she's graduating. She makes videos on YouTube of her singing and I REALLY want to use some of them in the video, but I have tried EVERYTHING to convert them into audio. I've tried using my computer to convert them, which actually worked, but I can't get the song to the IPad I'm making the video on. All I need is to get the songs onto my IPad. How?
