Not dwelling or complaining. Just merely stating what I've observed and to be truthful I am pretty concerned with her vocal issues because I do not wish to see her vocals get affected further. (BECAUSE I HAVEN'T SEEN HER LIVE IN PERSON YET! lol, I'm just hoping that if she ever had a live performance some time in the future, I could be there and her vocals wouldn't be more damaged than this, you know what I mean?)

Yes, I would concur that her songs utilizes different pitches and they're not easy to sing. She nailed Across the Universe. I really like that cover. I might like this cover more than With or Without You. I've got no love for Fly Me to the Moon.

Speaking of other artists covering her songs, someone actually covered Kettobase? I've got to check that out. Hopefully it's on YT. Definitely not an easy song to sing.

With all that said, the overall experience wasn't ruined at all. The live streaming on the 8th felt magical and I was really glued to the laptop. Despite frustrations due to lagging and disconnections and her damaged vocals(I just had to point that out! lol), it was fantastic. And yes, such issues would obviously not affect my love Utada, after all, she's the only pop artist that I like.
