51. Death Cab for Cutie: Transatlanticism (Barsuk, 2003)
Ben Gibbard's twee voice delivers some of the most poignant lyrics in indie-rock (though after this album, the band inevitably made the leap to the majors and has been on Atlantic ever since). All of Death Cab's albums are wonderful, but this one's where their production values and songwriting intersected with the zeitgeist for maximum impact.
