Which of these bands/artists is the worst?

[Oswald Acted Alone, You Kook]

All 16 of these acts have been discredited and condemned since their respective heydays, but of them, which one is the worst?

I personally like or tolerate at least one song from several of these acts, but I don't really know who is the worst. I think I'll go with T-Pain since he had the most damage on music as a whole while the others only damaged themselves. (Except Crazy Frog, where the novelty just got old, and Sugarland, who were victims of unfortunate circumstance)

[I’m not Stu]

I like Ashlee Simpson and Jennifer Nettles.

[Lambsbread]

Bro Limp Bizkit has some riffs y'all are nuts.

Puddle of Mudd and Hinder are both hot garbage so it was a tossup. Voted for Hinder because I remember despising them as a kid whereas Puddle of Mudd has never been anything more than just a weirdo band for weirdos.

[Samof94]

I like Ashlee Simpson and Jennifer Nettles.

I voted for her because she screwed up her SNL bit with lip syncing. Not a horrible person like some of the others on the list. Had the SNL gone differently, she’d be in better shape career wise.

I, proudly, don't know what a Hinder, Crazy Frog and Sugarland is.  I only know most of the others by name.  Of those I actually know anything about, (and using "worst at music" as the metric), probably Vanilla Ice.  I have no idea what most of these people did to get "discredited" so can't really judge for "worst human".

[Never Made it to Graceland]

Toby Keith did the most damage to American with that stupid boot in your ass song about killing Iraqis as revenge for 9/11.

He performed for Trump.
