Throughout its 121 episodes, every cast member was exceptionally talented.
But even with more than 700 songs covered, these how missed some pretty enduring and beloved hits. For example, many fans expected Rachel to sing Celine Dion's seminal tune "My Heart Will Go On," but it never came to . Just like that, there are several other songs the show didn't do, and there's an entire Reddit thread with some of the most prominent ones. As a note, some of these songs were released after the show's ending, but they are still fun to consider.
In The Air Tonight - Phil Collins
Phil Collins' seminal classic, "In the Air Tonight," served as his debut solo in 1981. The song became immortal thanks to the urban legend surrounding it, which claims it talks about a drowning incident where an onlooker could've helped but didn't.
Blaine Anderson had no shortage of solos during his time in the show, but Redditor glitterlovegal thinks his voice would've fit this particular song. And considering Darren Criss did a memorable rendition of Collins' Against All Odds, they may be on to something.
Into The Unknown - Frozen
Rachel Berry's voice fits Elsa like a glove. A Redditor, who since posting the thread deleted their profile, its 2013 predecessor, "Let it Go."
Coincidentally, Rachel also sang "Let It Go" during the season six premiere, so her singing "Into the Unknown" is a no-brainer. But, alas, a time machine would have been needed for this number to have been performed.
Bang Bang - Jessie J Feat. Ariana Grande & Nicki Minaj
In a thread of their own, glitterlovegal suggests numerous songs the show should've covered. Among them is this 2014 mega-hit which climbed to number #3 on the Billboard Hot 100. Sung by Jessie J, Ariana Grande, and Nicki Minaj, the song would fit the Unholy Trinity Perfectly.
A performance like this would likely include a killer dance number, and every fan knows the Unholy Trinity could dance like no other on the show.
About You Now - Sugarbabes
And speaking of the Unholy Trinity, fans wished they would've had more group numbers. Songs like "Come See About Me" and "Toxic" live rent-free on the heads of Quinn, Brittany, and Santana's fans, but the show could've showcased their talent and chemistry more.
To this end, Redditor classified12345 suggests Sugarbabes' "About You Now." They also think MKTO's "Classic" would've sounded good with Artie and Puck's voices, and it's an intriguing idea.
The Lion Sleeps Tonight - The Tokens
The charming and playful tune "The Lion Sleeps Tonight" came out in 1961 and remains as popular as ever, sixty years after its debut. Over the years, the song appeared in everything from The Lion King, so it's a tad surprising that it never made its way to the halls of McKinley High.
Redditor EthanPullenayegem also wants the song in Glee. He believes it would've been a great group number, even if he's not quite sure who would've sung it. The high notes have Kurt written all over them, but the rest of the song is up for grabs.
Rewrite The Stars - Zac Efron & Zendaya
Glee would've wasted no time covering more than one song from The Greatest Showman's beloved soundtrack. "This Is Me" has everything to be a New Directions group number, and knowing the show, the kids would've probably dressed in full costume to perform it.
But Redditor Gleek55 is also right when suggesting "Rewrite the Stars." Furthermore, they hit the nail in the head by suggesting either Finchel or Klaine sing it. The plot writes itself, and any fan of the show can see either of these two couples belting out the romantic duet.
She Used To Be Mine - Sara Bareilles
Waitress, based on the 2007 movie of the same name, premiered on Broadway in April 2016. With music and lyrics by underrated musical talent Sara Bareilles, the musical follows pregnant waitress Jenna Hunterson, who enters a pie-making contest looking for a way to start fresh.
The musical's pivotal number, "She Used to Be Mine," is a power ballad that talks about Jenna's hopes and fears. Redditor Tomidnight suggests Santana sing the tune, although Rachel could also have been a good choice. Marley, Mercedes, Kurt, and even Tina could also deliver worthy renditions of the song.
Come And Get It - Selena Gomez
Selena Gomez made a splash in the music scene with "Come and Get It." Critics viewed it as a departure from Gomez's previous Disney persona and welcomed her venture into more mature territory. "Come and Get It" peaked at number 6 in the Billboard Hot 100, giving Gomez her first Top Ten entry on the Chart.
In her thread, glitterlovegal suggests Rachel could do the song justice. It's an intriguing concept because Rachel wasn't known for her dancing abilities, and Gomez usually accompanied "Come and Get It" with elaborate choreography.
Lady Marmalade - Mýa, P!nk, Lil' Kim, & Christina Aguilera
In 2001, four pop stars ed forced to cover Patti Labelle's iconic "Lady Marmalade." The song, released in of the film Moulin Rouge!, reached #1 at the Billboard Hot 100 and earned all four performers a Grammy Award in 2002. Nowadays, many critics consider it one of the best female collaborations in modern music.
Redditor Lylyluvda916 believes the Unholy Trinity plus Rachel and Mercedes would've done the song justice. It's hard to go against that logic, especially because Rachel and Mercedes would've murdered Christina's part. But, alas, and unless there's a reunion of the show, fans will never get to hear the Glee Cast Version of this timeless hit.
