Spice Girls.
The Offspring - Half Truism
Opeth - Godhead's Lament. I usually don't like growling lyrics all that much (see: Cannibal Corpse), but Mikael... he's a God. You can actually hear what the fuck comes out of his mouth. You usually do not, which, to me, sounds like crap. Usually, the bands don't even need to have lyrics when the vocalist growls, because you can't hear what the hell they're trying to say anyway (again, see: Cannibal Corpse).
...Why can't/don't everyone growl like this? D:
But that's just me. No hard feelings.
