Lyrics:

Too late to let you know, what you mean to me
If I cried I'd only make you believe I was happy
I've got to let you go, and my heart, it aches
But it's worth it, 'cause I swear to god, you're a mistake

Know there could be a day, when the pain will fade
But a part of me is lookin' for you, back on yesterday
I've got to get away, 'cause my heart, it burns
And I know if I keep stickin' around, I won't ever learn

Don't wanna cry
'Cause, baby, I
Can feel freedom when they play

The real folk blues
I need the pain
My unhappiness is proof I'm not insane
'Cause when I'm close to you
I swear, I could die
Need to live my life, yeah, live like I'm alive
And it's a lonely road
Good luck and goodbye

[Cowboy Bebop] The Real Folk Blues (English Cover by Sapphire)
