You know, like when Born To Run stops, and then Springsteen just jumps in with THE HIGHWAY'S JAMMED WITH BROKEN HEROES ON A LAST CHANCE POWER DRIVE and, if the song's playing on the radio, or in a shitty bar somewhere or something, for a minute everything just crystallises into something much more and everything takes on some sentimentalist importance.
Other examples: When Dylan says, "I don't believe you... you're a liar." Or, a more modern example - having just read the review of the Brothersport single on here, it reminded me that that song does have a fantastic bit when it drop around the 2:58 mark when it reaches a lovely cloudy plateau and floats around for a bit. It's nice up there.
I'm sure you lot can list better examples.
