I do it all the time, sometimes with songs that I've known half my life- and never before realized how perfect is a certain turn of phrase, or a wonderful chord progression or the pathos of a certain line... For instance, there is a verse in 'A Touch of the Past':

"I can feel all the sadness of the traveler
Who has gone far away from his home
And he knows he can never return there
For the place and the people are gone"

that just gives me shivers.
