'Supergirl'

As if news of another crossover wasn’t exciting enough, the producers of the CW shows, “The Flash,” and “Supergirl” announced they will be making their early 2017 mash-up a musical event! So many of the actors on these two series have serious pipes and to mix that with their already fierce superior characters? Well, it’s going to be beyond epic.

One major question remains: What will they sing? With the crossover taking place over both shows, there’s plenty of room to belt out some solid tunes. Producers have said they’d like to mostly feature cover performances of songs you already know — though there is room for an original or two.

As avid viewers of both shows, Zap2it has unleashed our “Flash” and “Supergirl” experts — who happen to have wildly different tastes in music, it turns out — to create the ultimate dream playlist for the two-part event. With Broadway alums and former “Glee” stars rounding out the casts, this is going to be big and deserves the music to match.

‘Supergirl’

‘Hello’- Adele

Bringing back Tony Award-winner Laura Benanti as Alura Zor-El in a flashback — or some sort of alien ghost form — to sing this power ballad with daughter Kara (Melissa Benoist) would bring on the feels. Just thinking about their beautiful voices singing, “Hello, from the other side,” from their respective realms already makes us tear up a little.

‘Formation’- Beyonce

This would be Lucy Lane’s (Jenna Dewn Tatum) time to shine. Now, that she’s the acting head director of the D.E.O., Lucy is the Queen B of National City. Plus, with Tatum’s extensive dance background, this could be a showstopper of a performance with her army of agents dancing “in formation” behind her.

‘Stay With Me’- Sam Smith

Jeremy Jordan got his start on Broadway, receiving both a Tony and Grammy nomination for his portrayal of Jack Kelly in “Newsies,” so he would kill an acoustic version of this love song.

After getting duped by Siobhan (Italia Ricci) — and realizing that Kara will never reciprocate his feelings for her — it’s safe to say Winn is going to date around and, bless his heart, will probably keep seeing girls who take advantage of his noble self until he finds someone he truly deserves.

‘Started from the Bottom’ – Drake

The crew on “Supergirl” are now finally on the same page with the same goal. We picture James Olson sitting in his office — basking in the joy of his Supergirl love, while reveling in Superman’s return — and he could bust out with this Drake hit through a montage of Season 1’s rougher moments.

Even if this happy moment only lasts until the next commercial break, a time to recognize all they accomplished together would be empowering.

‘The Flash’

‘Flash’ – Queen

Okay, so this one is a bit tongue-in-cheek, but imagine this song as sung by the entire cast in a big group number, complete with choreographed dance moves? “Flash! Ah! Savior of the multiverse!” Admit it, you’d sing along.

‘Open Your Eyes’ – Bobby Caldwell

While “Supergirl” and “The Flash” are loaded with talented singers, did you know Carlos Valdes — aka Cisco Ramon — has albums. He’s released two EPs and in 2015 even put out a cover of Bobby Caldwell’s 1981 track “Open Your Eyes,” putting a modern spin on it.

If you have Valdes on the show, you may as well have him singing some of his own work. Besides, maybe Cisco will have a special someone in his life to sing to.

‘Touch of Grey’ – Grateful Dead

This may be a bit of an obscure pull for younger fans, but we imagine this as a song Joe sings to Barry when whoever they’re battling has got him down and close to giving up.

On it’s surface, “Touch of Grey” is a song that looks at the negatives in life, embracing them. However, it always comes back to the refrain of “It’s alright” and “We will get by.” It’s a message Barry often needs when his deadliest foes come close to toppling him.

‘Misery’ – Soul Asylum

Let’s be honest, while Barry may be a superhero, he’s got the absolute worst timing when it comes to love. He wants to be with Iris, she seemingly wants to be with him, but there’s always a wrench thrown in the works, which makes “Misery” a perfect choice for his own solo. Misery loves company and Barry could certainly use some.

“The Flash” returns Tuesday, Oct. 4, at 8 p.m. ET/PT while Season 2 of “Supergirl” premieres on Monday, Oct. 10, at 8 p.m. ET/PT on The CW.
