Yo! I couldn't sing a song to save my life. You know how birds fly to Cinderella when she starts singing? They would literally drop dead if they heard my singing voice. You could ask me to hum a song and you'd immediately regret it and tell me to stop. It wouldn't be the sound of music. It would be the sound of distress. To be honest, I rather eat a Carolina Reaper than to attempt to sing a song.
I remember my elementary school music teacher asking me to sing quieter because it was so bad. And instead of The Voice, the croak. I have no doubt that you'd unfollow me in a heartbeat if I started singing. Anyway to answer your question, no I haven't done any singing.
