Autotuned: Justin Bieber versus Black Keys in post-Grammy 'Twar'

There's gold on the ceiling for rockers The Black Keys, and not a lot of praise for it from young YouTube-made millionaire Justin Bieber, who lashed out in a "Twar" (Twitter War) of words.

The Black Keys drummer Patrick Carney spoke of the Canadian heartthrob after sweeping major categories at the Grammy Awards on Sunday.

The band stepped out to celebrate. This was when Carney decided to comment on the fact that Bieber was snubbed by the Recording Academy this year.

"He's rich, right?" Carney said when TMZ.com asked if Bieber should feel burned. "Grammys are for, like, music, not for money ... and he's making a lot of money. He should be happy, I guess."

Not so.

On Tuesday the "Boyfriend" singer tweeted: "The black keys drummer should be slapped around haha."

Many critics have noted that Bieber needs to be reminded that his music is pure pop, auto-tuned and not even written by him.

Bieber is convinced because he is one of the hardest-touring people in music, recording incessantly that the Grammy Awards should recognize him.  Yet most industry critics find it ridiculous that Bieber is in a snit because of another person's opinion.

The young singer who was discovered on YouTube and rose to prominence via social media, has had albums have topped the charts and gone platinum.
