Carrie Underwood explained to msn.com why her voice sounds different on this song: "You get different feelings from different songs, and that one always just felt soft and vulnerable. It's a song about being disappointed. And, yeah, it's not so vibrato-heavy - but I guess it's good that I can do something that sounds different, maybe something surprising."
Ten years after Carrie Underwood recorded the song, Rascal Flatts put their own spin on it, covering the tune for their 2017 Back To Us album.
"Piano Man" was inspired by Billy Joel's time playing at a piano bar in Los Angeles. The "real estate novelist" was a guy who always talked about writing a book, but spent all his spare time in the bar.
The Boyz II Men hit "It's So Hard To Say Goodbye To Yesterday" is an a capella cover of a song from 1975 by G.C. Cameron that was used in the movie Cooley High to express the feeling of parting ways with high school friends.
"It's the End of the World As We Know It (And I Feel Fine)" was inspired by a dream where Michael Stipe conjured up images of people with the initials L.B.: Lester Bangs, Leonid Breshnev, Lenny Bruce and Leonard Bernstein.
