BEST PART - DANIEL CAESAR / H.E.R

[...]

You don't know, babe

When you hold me

And kiss me slowly

It's the sweetest thing

And it don't change

If I had it my way

You would know that you are

You're the coffee that I need in the morning

You're my sunshine in the rain when it's pouring

Won't you give yourself to me

Give it all, oh

I just wanna see

I just wanna see how beautiful you are

You know that I see it

I know you're a star

Where you go I follow

No matter how far

If life is a movie

Oh you're the best part, oh oh oh

You're the best part, oh oh oh

Best part

It's the sunrise

And those brown eyes, yes

You're the one that I desire

When we wake up

And then we make love

It makes me feel so nice

You're my water when I'm stuck in the desert

You're the Tylenol I take when my head hurts

You're the sunshine on my life

I just wanna see how beautiful you are

You know that I see it

I know you're a star

Where you go I follow

No matter how far

If life is a movie

Then you're the best part, oh oh oh

You're the best part, oh oh oh

Best part
