Black Eyed Peas superstar WILL.I.AM uses Twitter.com to do more than update fans on his daily routine - he organises tour dates and checks reactions to his music via the microblogging site.
The frontman is a huge fan of the social networking site because he can instantly see what devotees want from his band through their Tweets.
And he reveals calls from Brazilian users for the group to perform in their homeland led the Black Eyed Peas to head to the South American country for the first time.
He tells Britain's The Sun, "This (phone) has everything I need. I read Twitter all the time, even though I rarely Tweet. I even gauge response to new songs and countries we need to play in through it.
"We planned our last tour through Twitter. We had Tweets from Brazil saying we never go there, so we decided we'd put on shows there right away. I'll always be looking ahead, whether it's with technology or my music."
