How did we get back again? 
 How'd we get mixed up in the first place? 
 The window's openin' 
 You can't spread your wings in a bird cage 
    We get high and we go down again (ooh, we go down again) 
 We go 'round and right back where we been 
 And the days go by, the nights, they never end 
 Do it all again (do it all again), mm   
 'Cause when it's on sight, it's on sight 
 All of it, all of it, can't wait 
 It's a celebration like it's a birthday (it's a birthday) 
 So amazin', I just wanna taste it 
 Let's celebrate in the best way 
 Like it's your birthday   
 Oh (all I see is you now, all I see is you now), in the first place 
 Oh (don't wanna lose you now), and that's the worst case 
 Oh, yeah (birthday, birthday, birthday) 
 Oh, yeah, oh, yeah (it's your birthday, birthday), in the first place   
 Where do I begin? (Oh) 
 Been this way for a long, long time, oh 
 Something's got to give (something gotta, something gotta give) 
 'Cause you keep on tickin' on my mind, oh   
 We get high and we go down again (we go high, we go high) 
 We go 'round and right back where we been (right where we been) 
 And the days go by, the nights, they never end (the nights, they never end) 
 Do it all again, do it all again, mm   
 'Cause when it's on sight, it's on sight 
 All of it, all of it, can't wait 
 It's a celebration like it's your birthday (it's your birthday) 
 So amazin', I just wanna taste it 
 Let's celebrate in the best way like it's a birthday   
 Oh (all I see is you now, all I see is you), in the first place 
 Oh (don't wanna lose you now), don't wanna, don't wanna, that's the worst case (and that's the worst case) 
 Like it's your birthday, birthday, birthday, babe 
 Like it's your birthday, birthday (oh, in the first place)
