There's no denying that Hayley Williams has a nice set of pipes (and her singing's pretty good, too... *rimshot*). They do have some fun songs as well; I like them better when they're channeling Cheap Trick ("That's What You Get", "Misery Business") than when they try to be balladeers. And they didn't break up, but two of the founding members left the band recently. It seems I know way more about Paramore than I feel comfortable with.
Here's some more Great Moments In Vocal History:
Tool -
Pushit (the part starting at about 8:27 wrecks me every time)
Mayfield Four -
Inner City Blues - Myles Kennedy is the best rock singer alive, and he used to be in an amazing band called Mayfield Four that made great music, and none better than this Marvin Gaye cover. He is now in a not so amazing band called Alter Bridge, which is the band the former members of Creed started after Scott Stapp left. I miss Mayfield Four.
Brandi Carlile -
The Story - Brandi Carlile has just a great voice in general, but when she gets to the part at 2:53 and her voice cracks I get goosebumps.
The Decemberists -
The Wanting Comes in Waves - Don't worry, Cron, I'm not talking about Colin Meloy's voice on this one. I'm talking about the backup vocals provided by Shara Worden, of the band My Brightest Diamond. She first comes into the song around 2:08, and her voice is so fucking powerful and Grace Slick-y. I saw them live shortly after Hazards of Love came out, and her voice was even more amazing live. Also great in this song is Becky Stark, whose background vocals start around 4:17.
EDIT: I forgot to include my favorite voice of all voices, J Tillman:
