Beyoncé and Miley Cyrus' 'Cowboy Carter' reaches No. 1. What's it about?

Beyoncé collaborates with country music artists on her new album, “Cowboy Carter,” including Miley Cyrus.

Cyrus is featured on track “II Most Wanted” and it's becoming one of the breakout tracks on the album.

The accolades are warranted, fans are saying already.

"II MOST WANTED must be studied!! The way Miley Cyrus and Beyoncé’s voices collided and seamlessly intertwined," a fan tweeted.

"I could literally cry listening to this," another chimed in.

"Miley put back (on) her Hannah Montana wig and left NO crumbs !" a third person wrote.

What is Beyoncé and Miley Cyrus' song 'II Most Wanted' about?

It's a love song about lasting companionship. As Hoda Kotb wrote on Instagram of the song, "Crank this up and think of your bestie."

The two singers alternate lines on the track, using the idea of riding shotgun — or in the front passenger seat — to show their love and continued commitment, even as they get older.

“I don’t know what you’re doing tonight but I’ll be your shotgun ‘til the day I die," they sing together.

Have Beyoncé and Miley Cyrus collaborated before?

Cyrus has spoken with admiration about Beyoncé in the past. During a 2007 interview with Oprah Winfrey, she said her mom, Tish Cyrus, was “in love with Beyonce." Miley Cyrus, then 14, said Beyoncé was her mom's “favorite person in the world.”

Tish Cyrus used Beyoncé as a role model for her teenage daughter.

“My mom brings me every article. Look, she’s so humble but she’s so amazing. She brings me all those positive people,” she said.

The two were once part of a 2008 supergroup along with Rihanna, Carrie Underwood, Ciara, Mariah Carey, Mary J. Blige (and more). They performed the charity song “Just Stand Up!" at the "Stand Up to Cancer” telethon special and stood side-by-side at a live performance.

"Cowboy Carter" also features a song written and originally recorded by the Disney alum’s godmother, Dolly Parton.

Parton’s 1973 song “Jolene” is listed on the “Cowboy Carter” tracklist. Parton's own voice is on track "Dolly P" in which she introduces "Jolene."

"You know that hussie with the good hair you sang about," Parton says on "Dolly P," a reference to a Beyoncé lyric from her 2016 album "Lemonade."

Parton sang about a similar dynamic on her landmark song "Jolene."

"Reminded me of someone I knew back then, except she had flaming locks of auburn hair, bless her heart. Just a hair a different color, but it hurts just the same," Parton says to close the track.

Parton previously signaled that the cover would be on the album.

“Well, I think she has!” Parton told the Knoxville News Sentinel earlier this month. “I think she’s recorded ‘Jolene’ and I think it’s probably gonna be on her country album, which I’m very excited about that. I love her! She’s a beautiful girl and a great singer.”

Fans expected several collaborations after Beyoncé confirmed the possibility in a March 19 Instagram post about the album as a follow up to “Renaissance.”

“I have a few surprises on the album, and have collaborated with some brilliant artists who I deeply respect,” she said.

“I focused on this album as a continuation of ‘RENAISSANCE,’” she added. “I hope this music is an experience, creating another journey where you can close your eyes, start from the beginning and never stop.”

The “Party In The USA” singer has had a big year in addition to now being on a song with Beyoncé. She earned her first two career Grammys at the 2024 Grammys Feb. 4, during which her song “Flowers” took home best pop solo performance and record of the year.

While accepting her award, Cyrus told a story about a boy trying to catch a butterfly with his net, to no avail until he stopped trying.

“With no luck, he sat down the ground, he finally let go, and he surrendered. And he was OK that he wasn’t going to capture this beautiful butterfly,” she shared. “And right when he did, is when the butterfly came and landed right on the tip of the nose.”

“This song, ‘Flowers,’ is my butterfly,” she said in closing before proudly holding up the golden statue.
