Chaka Khan Flips the Scri...Exclusive)

Chaka Khan is flipping the script on Godzilla.

About seven years after releasing her last studio album, the 73-year-old Rock & Roll Hall of Fame member is back with a new single called "Chakzilla," co-written with Sia, who also provides backing vocals."When I was a kid, I really liked the Godzilla movies," Khan tells PEOPLE. "When we came up with ['Chakzilla'] as a title, lots of things just ran through my head and made a lot of sense."

Khan wrote "Chakzilla" with Sia, 50, who came up with the title. "I would've never thought of that," she says. "She's clever. She comes up with lots of ideas."

The two artists worked together on Khan's upcoming album, also called Chakzilla, which comes out on Friday, Sept. 18 via BMG Rights Management. "It's a really, really great album, a great CD with great songs. It's going to be on the pop dance side," she says of Chakzilla, her first full-length project since 2019's Hello Happiness. "We've got lots of great people collaborating as well."

Sia tells PEOPLE in a statement, "Chaka is the Godzilla of chanteuses alive, and it was my honor to collaborate with her on this music!"

Chaka Khan – CHAKZILLA ...ius Lyrics

I been waiting all my life for this moment
I been waiting all my life for this romance

I been waiting till I could let my hair down
I been waiting for you to come around

You’re the kind, you’re the kind that I like
Creature of the night, creature of the light, light
You’re the sign I like
Aura shining bright, aura shining bright bright bright

I know that I am great
(I’m a giant, I’m a giant)
I know the rules I’ll break
(I’m a giant, so come up come up come up)
Forever my heart aches
(I’m a giant, I’m a giant)
Cos you’re my equal babe
(I’m a giant, so come up come up come up)

So come up come up come up
So come up come up come up
I’m a giant
I’m a giant

Been waiting for a giant like mama
I been waiting for who comes with no drama
It was winter and now every day’s summer
I been waiting to get laid in this number

You’re the kind, you’re the kind that I like
Creature of the night, creature of the light, light
You’re the sign I like
Aura shining bright, aura shining bright bright bright

I know that I am great
(I’m a giant, I’m a giant)
I know the rules I’ll break
(I’m a giant, so come up come up come up)
Forever my heart aches
(I’m a giant, I’m a giant)
Cos you’re my equal babe
(I’m a giant, so come up come up come up)

So come up come up come up
So come up come up come up
I’m a giant
I’m a giant

I know that I am great
(I’m a giant, I’m a giant)
I know the rules I’ll break
(I’m a giant, so come up come up come up)
Forever my heart aches
(I’m a giant, I’m a giant)
Cos you’re my equal
I’m a giant
I’m a giant

"If you can't say anything nice, then don't say anything at all..."
i actually, literally mis-heard the lyric as "I'm tryin', I'm tryin'"
