Watch A Cruise Ship Belt Out 'Seven Nation Army' [video]

Each year, the Port of Hamburg (Germany) throws a huge party to celebrate its opening in 1189, and this year marked the port's 825th birthday. Now we're not sure how past anniversary celebrations went down, but the MSC Magnifica cruise ship sure helped ensure that the event grabbed our attention this year. At first, the 964-foot, $547-million cruise ship looks to be just another boat cruising through the harbor, but then its horn belts out an amazingly awesome version of the guitar riff from Seven Nation Army by The White Stripes,  which we found thanks to Gizmodo. As good as this highly addictive bass line sounds in the song, hearing it blare from the cruise ship horns is even more awesome.

According to the official video released from the event, which took place May 9-11, 300 ships were cheered on by a crowd of more than a million who were in attendance. RELATED: Watch The Slowest Massive Boat Crash Ever
