MTV’S MARCH MADNESS: Thirty Seconds to Mars, Arcade Fire, Foo Fighters and Linkin Park are the #1 seeds in MTV News’ second annual Musical March Madness Tournament. Much like the NCAA basketball tournament on which it is based, the MTV variant will span three weeks as fans vote on who they want to see advance to the championship game on April 4, the same night as the Final Two showdown. Fans can vote online here and use the official Twitter hashtag #MMM to spread the word. Cobra Starship’s Ryland Blackinton and Alex Suarez return to offer their analysis, as they handicap the race below. Last year, Coheed and Cambria took the title after more than 2 million fans registered their votes. For more info, go to MTV News. (3/14p)
