Euph, just for you, gag on THIS:
I have begun indoctrinating my 2-year old grandson into Josh Groban's beautiful, soulful music. I attribute it to you, and to a lesser extent all the GUYS on this thread dissing my boy Josh.
My husband and son, when informed of my plan, said at least Groban beats the hell out of rap. 
Seriously, I'm delighted that you enjoy MUSIC - that nebulous, indefinable thing that can inspire us and guide us in all kinds of ways. And I agree that Groban's stuff is better than rap, but that's hardly a comparison since the sound of cats fighting is better than rap.
I and Mrs E both shake our heads at the commercial "success" of Groban. Both of us know far, far too many artists with more chops, more skills, more training, more practice, and more artistry than that boy will ever see.
And from that perspective, that's the tragedy that I'm describing.
For that matter, we can apply that same basic concept to most commercial "successes" these days, to include Bieber, Aguilera, and the rest of those teen "stars" that manage to bubble through the system like so many farts in a bathtub.
