I don't have any songs that are 0:45...
However...I almost have all of the national champions!
3:30 - "You Shook Me All Night Long" (AC/DC, Back in Black)
1:07 (67) - "Mean Mr. Mustard" (The Beatles, Abbey Road...actually 1:06, but that's close enough for me!)
5:03 - "Crumbs From Your Table" (U2, How to Dismantle an Atomic Bomb)
My longest song is "Mountain Jam" (The Allman Brothers Band, Eat a Peach) at 33:41!
