(CNN) -- This is the summer of Auto-Tune. The Gregory Brothers have become a viral hit with their "Auto-Tune the News" videos. No matter how hard some people -- notably Jay-Z --have tried to kill the trend of musicians using computers to make their voices sound like whiny robots, Auto-Tune technology continues to ride a cultural high. Now the voice-altering effects are migrating from recording studios to YouTube and mobile phones. An iPhone app called "I Am T-Pain" lets people manipulate their voices to sound like the popular rapper and Auto-Tune advocate. The Gregory Brothers, a sibling band out of Brooklyn, New York, has become a hit on YouTube with a series of videos that Auto-Tune cable newscasts and political speeches.

And if you can get five minutes of the day at work ... to get a couple yucks in, I think you'd rather do that than watch your latest @placeholder conspiracy movie or something.
