@beardalaxy @lain perhaps so, but i ask you to consider (this is a personal by me for me cope post)

modern ears are used to listening to the "perfect" recordings with 5000x layers of editing, of various artists, on headphones, but realistically this is how all singers sing performing with movement after 30+ minutes of performing. Lady gaga, duran duran, eurovision, rammstein, song performances generally have 3-10+ "errors" in the singers voice alone in live (albeit recorded super professionally and live-fixed with algorithms), all these errors dont exist as the brain ignores them in real life with ears. but the brain is hyper fixated and noticeable with headphones, where its used to listening to near-perfection quality audio.

a band's singer(s) cant very pitch accurately hear themselves, and the audience generally cant notice either. add to this, a phone's microphone, which is a super tiny hole somewhere in a weird direction, which causes pitch shifting. Something simpler, like ABBA music, where vocals are the prime and every instrument supports the vocal harmony/harmonies always, is much easier to sing properly while playing it, yet in live recordings i still hear lots of slight pitch mistakes at the start of certain notes (which then raise or lower to the proper value VERY quickly thanks to the instrument backing)

meanwhile, duran duran is quite complex as a lot of it is mixing between various levels of loose pitch singing and portamentos and fixed flat pitch singings (like the chorus for Invisible)

i say this all knowing that even with a perfectly tuned guitar ill fail so many spots in singing something really simple like "house of the rising sun" unless ive specifically practiced it like 10 times in the past 48 hours beforehand (same for most other songs too)

I dont know how much, or if at all, people realize this when they hear me live.

but i know that when i sometimes for fun record myself with a good mic, im cringing to death and want to kill myself, hearing a rate of one obvious mistake per 5 seconds on a good recording

someone like pavarotti (RIP) is the perfect example of a perfect live performer for the PoV on vocals: instrument backing is classical music which will near-always fully support the vocal, the vocal is the prime so the singer always hears with 100% perfect clarity what he is singing, and its all he practices day and night every week of his life; a master of one feature to perfection, held even more up with a supporting environment
