While Black Sabbath was an obvious choice for the trailers and closing credits of Robert Downey, Jr.'s 2008 blockbuster Iron Man -- you know, because one of their biggest hits is "Iron Man" -- Australian hard rockers AC/DC are the ONLY act on the soundtrack to Iron Man 2, contributing 15 songs from their catalog.

The Louisiana teen who opened fire in a crowded middle school classroom yesterday before attempting suicide wrote that he wanted to join the Marines, and professed a love for rockers Marilyn Manson and AC/DC, according to the Thibodaux Daily Comet<

We've already revealed our most important albums, songs, and videos of 2008, but what music garnered your interest this year?

AC/DC had a great year. There was a best-selling album, a sold-out concert tour, and now lead singer Brian Johnson is preparing to write his memoirs.

AC/DC certainly know where their fans shop. Black Ice, the time-honored rockers' first album in more than eight years, sold 784,000 copies during its first week, earning the band their second No. 1 album -- and first chart-topping debut ever! What's more, the album is being sold exclusively via Wal-Mart, Sam's Club, and online via AC/DC's official web site. Whoa!

In my confirmation email from the record label representative, I was told that travel from Manhattan to Wilkes-Barre, PA, ("Wilkes-Berry?" "Wilkes-Bar?" Actually, it's "Wilkes-Bear-Uh") and back for an exclusive AC/DC performance Sunday night would be by VIP Bus.
