I 愛 歌う but my iPad camera is shaky, I don't have a YouTube account (and I'm not allowed one), and I don't have a video camera. What should I do?

あなた could maybe get a microphone and download "Audacity" (or some other voice recorder), as if あなた are shy または quiet あなた can use the program to make your voice louder and it's easy to use just plug in a mic and press record.
Also for the background/main thing maybe one sings close to the mic whereas the other is further away?

hmmm wait for good one

You. Should sing
