What’s With The New Vocal Style?

The one where the singer sounds like he ate a five pound burrito with too much processed cheese, hasn’t had any fiber for a week and is singing from the toilet?  You know, the Nickelback/Theory Of A Dead Man sound.  I address them as a single entity as it must be the same lead singer, right?  There’s no way that more than one person would have actually been coached into that vocal style.  If you’re really straining that much while singing, maybe it’s time to give it up.
