Sure, there were only so many Britney Spears songs that Glee could squeeze into its latest tribute, “Britney 2.0” especially since the episode featured eight songs as it was, which is not exactly a small amount. Still, we’re a tad bitter that a bunch of our favorite Britney hits somehow got left out. And we could either cry, cry, cry in our lonely hearts about it, or we could speak up.

So here are our Top 6 neglected Britney songs, in order of how badly we wished they could have been performed on Glee. Not that it's too late, right? (Did someone say, “Britney 3.0”?)

6. “Till the World Ends”

Watch the original music video here!
Year of release: 2011
Who would sing it: Brittany (Heather Morris)
Here’s why: Does anyone possibly know why an episode based around Brittany could neglect to use a song with the word “dancing” in the chorus? We don't either.

5. “If U Seek Amy”

Watch the original music video here!
Year of release: 2009
Who would sing it: Santana (Naya Rivera)
Here's why: Why bring Santana back but not give her a song? And this one would have been completely appropriate for her, given the oh-so-sexy message with lines about how “all of the boys and all of the girls” are begging to... well, everyone can spell, right? In fact, maybe the show could have even added a character at Louisville named Amy for the song to really make sense, kind of like how Finn (Cory Monteith) sang “Jessie's Girl” about Jesse St. James (Jonathan Groff).

4. “Piece of Me”

Year of release: 2007
Who would sing it: Blaine (Darren Criss)
Here's why: This was another top-20 hit for the Britster, and it was about dealing with being on top, which is something New Directions knows a thing or two about. Blaine could sing this to address the pressure of having to potentially lead New Directions, considering that Artie (Kevin McHalechose him to succeed Rachel. And let's face it – one more Blaine song never hurt anyone, right?

3. “I'm Not a Girl, Not Yet a Woman”

Watch the original music video here!
Year of release: 2002
Who would sing it: Tina (Jenna Ushkowitz)
Here's why: Any number of characters could relate to this song's lyrics, but we'd choose Tina, given the changes that she's faced of late. Plus, Glee seemed to be yearning for more Britney ballads, seeing as how they slowed down a number of Britney's faster songs in “Britney 2.0.” Also, this song would give us a chance to reminisce about the movie that it was featured in, Crossroads. (C'mon don't tell us that we were the only ones who saw that movie. 'Fess up!)

2. “Circus”

Watch the original music video here!
Year of release: 2008
Who would sing it: Rachel (Lea Michele)
Here's why: It's crazy that this song was overlooked since it's about being an entertainer, which is perfect for Glee. And Rachel would have been a natural to deliver lines like, “All eyes on me in the center of the ring.” Then again, after Finchel’s engagement debacle last season, it's probably best not to force Rachel to spend too much time thinking about the word “ring.”

1. “Lucky”

Watch the original music video here!
Year of release: 2000
Who would sing it: Marley (Melissa Benoist)
Here's why: Here it is the most egregious omission from the Britney catalog! Aside from being an all-around awesome song and a reminder that pop music was ridiculously fun in the year 2000 (sigh) the lyrics address dealing with the spotlight and hiding your true emotions. Rachel could definitely relate to that, since she knows what it’s like to have something “missing in my life” (ahem, Finn), but Marley would be perfect, given her rocky home life and her shyness.
