[Verse 1: Justin Bieber] Everybody's laughing in my mind Rumours spreading 'bout this other guy Do you do what you did when you did with me? Does he love you the way I can? Did you forget all the plans that you made with me? Cause, baby, I didn't [Chorus: Justin Bieber + Rascal Flatts] That should be me holding your hand That should be me making you laugh That should be me, this is so sad That should be me, that should be me That should be me feeling your kiss That should be me buying you gifts This is so wrong I can't go on 'til you believe that that should be me That should be me [Verse 2: Rascal Flatts + Justin Bieber] You said you needed a little time for my mistakes It's funny how you used that time to have me replaced Did you think that I wouldn't see you out at the movies? What you doing to me? You're taking him where we used to go Now if you're tryna break my heart, it's working cause you know that... [Chorus: Justin Bieber & Rascal Flatts] That should be me holding your hand That should be me making you laugh That should be me, this is so sad That should be me, that should be me That should be me feeling your kiss That should be me buying you gifts This is so wrong I can't go on 'til you believe that that should be me That should be me [Bridge: Justin Bieber] I need to know should I fight for love or disarm? It's getting harder to shield this pain in my heart [Chorus: Justin Bieber & Rascal Flatts] That should be me holding your hand That should be me making you laugh That should be me, this is so sad That should be me, that should be me That should be me feeling your kiss That should be me buying you gifts This is so wrong I can't go on 'til you believe that that should be me Holding your hand, that should be me The one making you laugh, oh baby Oh, that should be me That should be me giving you flowers, that should be me talking for hours That should be me, that should be me
