Background vocals are awesome! Just stand 1m away from the mic and sing a little bit! Nearly all recordings will sound dope af! Whenever I try to record "singing", I just do that. In general, I really like room recordings. They sound majestic somehow. I recorded so many sessions... Just chilling with friends in the studio, having some drinks and jam. I didn't tell them I was recording the whole evening. Pretty fun to listen to it. You can play around with stuff like that. For Intros and Outros its super cool I think.

I know that you're no taking yourself seriously :D
