Freddie Mercury!

This one is not likely to be popular here, but I have to be totally honest and say: Miley Cyrus.

Don't get me wrong. I am not really a fan of her or her music (nor am I a hater). But my god does that woman have an incredible voice and a mastery of how to use it.

Chris Cornell of Sohndgarden, Temple of the Dog, and Audioslave

I’m also always impressed by Demi Lovato

For me, has always been Chris Cornell. Absolutely gutted when he died, knowing I'd never hear anything new from him again.

Serj Tankien

I am a huge Soad fan, but his solo career also counts. The guy has a one in a billion voice, amazing range!

No one mentions Adele?

The chick from paramore

Hayley Williams of Paramore.

Especially since she started experimenting with solo projects. She's so good and very versatile.

Devin Townsend

I'm always amazed by Robert Plant when I watch old Zeppelin videos

James Maynard, I mean how big are his lungs?

Regina Spektor.

For my money no one can convey as much emotion through their voice as her.

Sara Bareilles

Is incredibly precise. Listening to her voice is like listening to what people are hoping for when they’re autotuning, but she nails it.

Jeff Buckley Ella Fitzgerald Edith Piaf

Mike Patton, he has one of the largest vocal octave ranges in music.

Elizabeth Fraser from Cocteau Twins.
Dolores O'Riordan (RIP) from The Cranberries.
Arai Akino, for "VOICES" from Macross Plus.

Tetiana Shmailyuk from Jinjer - a Ukrainian metal band. Her ability to go from her growl to her clean vocals is absolutely wild to me.

Hearing Bjork sing “Birthday” on the Sugarcubes’ debut LP was a revelation for me. Still blows me away.

Floor Jansen

Andrea Bocelli and Miley Cyrus.

The lead singer of the German band, AnnenMayKantereit. (The band name is just three surnames smooshed together.)

Here's my favorite song by them: https://www.youtube.com/watch?v=tERRFWuYG48&t=4 which translates to "barefoot at the piano"

Another great song, a bit more up-beat: https://www.youtube.com/watch?v=y6BmrRLpGJQ&t=3 which translates to "would you go out with me?"

Thom Yorke

Chaka Khan

The Söderberg sisters of First Aid Kit are pretty amazing.

Lzzy Hale has an incredible voice

Josh Kiszka of Greta Van Fleet has a hell of a voice.

I'm also surprised that I didn't see anyone mention Mariah Carey.

Hailey Williams. Wasn't even into that genre at the time, but her voice always made me think "wow, this is pretty good".

When Brandi Carlile’s voice cracks and she belts out the chorus near the end of The Story, it’s just incredible. There are better singers, technically, but the pure, raw emotion conveyed is powerful (to me anyway).

Till Lindemann always gives me the goosebumps.

no mention of bessie smith , billie, nina , janis joplin ?

That's gotta be Antwaun Stanley for me. His work with Vulfpeck and Cory Wong are just phenomenal

This Lewis Capaldi dude. He can freaking sing, man.

Haley Reinhart

Ann Wilson (Heart) always makes me smile when I watch her live performances.

Caroline Polachek, Imogen Heap, Charlie Puth, Kim Petras, and occasionally Sia.

Vocal powerhouses.

Dimash Qudaibergen. He has the most incredible voice I've ever heard.

Recently it's this girl. https://youtu.be/YYoP9bxwg84

Her voice is out of this world. Sadly I don't know how to write her name. [Symbol]OK

George Michael had an incredible voice and was my singing idol for a long long long time - I'm a contralto so I can't really sing to a lot of female singers unfortunately... His range and timbre... Just amazing.

Floor Jansen and Marcela Bovio, especially when they sing live.

Renée Elise Goldsberry aka Angelica Schuyler in Hamilton

Kristin Chenoweth and Idina Menzel from Wicked

Will Ramos

Linda Perry.

Lead singer of 4 Non Blondes and has a solo career. I don’t even listen to that style of music, but I still get excited when I hear her voice come on.
