I’m nominating Immigrant Song. Originally done by Led Zeppelin, covered by many, it clocks in at a measly 2:23 or so. Karen O and Trent Reznor covered it just over a year ago for The Girl With The Dragon Tattoo and they rocked it in 2:48, because of a little preamble. Take a listen. You can find it with a simple Google search. It’s a great way to blow an occasional two minutes.
