Nick Jonas does have an annoying voice, I agree with the OP.
Cher Lloyd, Jessie J, Ed Sheeran, and Sam Smith can also have annoying voices in my opinion. Iggy and Angel Haze have voices that can get grating also.
I hate Nick Jonas voice, it sounds so creepy I feel like he's raping me. It's so strained and abusive boyfriend-ish.
Jennifer Hudson always feels like she is yelling at me and it makes me uncomfortable.
Iggy, if she counts as a singer. So annoying too. Fancy, Black Widow and Beg For It are such bops. I wish they went to someone whose voice I actually liked.
bey has good technique but I really dislike her tone and that's why I can't get through any of her songs
Also Julianne Hough has the sharpest voice I've ever heard.
And Ellie Goulding is just Where do I begin

Cher Lloyd is very annoying and I agree Iggy is grating. Sam is alright, he sounds lie he has a head cold though.
How did I forget her? OMG i literally turn off the radio whenever she comes on it's a mess. Like does she just walk in the studio and whisper for a few mins and leave
Most of those trash singers they play on UK radio all the time like John Newman, Jess Glynne, Ella Eyre etc. they all sound the same and their voices are all so grating
