Lyrics:
Loving him is like driving a new Maserati down a dead end street
Faster than the wind, passionate as sin, ending so suddenly
Loving him is like trying to change your mind once you’re already flying through the free fall
Like the colors in autumn so bright just before they lose it all
Losing him was blue, like I’d never known
Missing him was dark gray, all alone
Forgetting him was like trying to know somebody you never met
But loving him was red
Loving him was red
Touching him was like realizing all you ever wanted was right there in front of you
Memorizing him was as easy as knowing all the words to your old favorite song
Fighting with him was like trying to solve a crossword and realizing there’s no right answer
Regretting him was like wishing you never found out that love could be that strong
Losing him was blue, like I’d never known
Missing him was dark gray, all alone
Forgetting him was like trying to know somebody you never met
But loving him was red, oh red, burning red
Remembering him comes in flashbacks and echoes
Tell myself it’s time now, gotta let go
But moving on from him is impossible when I still see it all in my head…in burning red
Burning it was red
Oh, losing him was blue, like I’d never known
Missing him was dark gray, all alone
Forgetting him was like trying to know somebody you never met
Cause loving him was red, yeah, yeah, red, oh burning red
And that’s why he’s spinning around in my head
Comes back to me, burning red, yeah, yeah
His love was like driving a new Maserati down a dead end street
