Here's a couple more that aren't on the list:

James Durbin - I'll Be There For You - American Idol 2011
Not sure how I feel about the popified arrangement, but Durbin's voice is very similar to Jon's to say the least. He's actually now the lead singer for Quiet Riot.



Sophie Stolte - Livin' on a Prayer - The Voice Kids Germany 2015
Fair warning, this one's a bit cringy.
