Luna has a tendency to make references to classic rock songs:
Luna saying "For those about to rock" in "No Guts, No Glori" was a reference to the AC/DC song "For Those About To Rock".
Luna told Lincoln "You can't always get what you want, bro" in "Project Loud House". It's a reference to The Rolling Stones' song "You Can't Always Get What You Want".
Luna saying "Yeah, every little thing is gonna be alright" references Bob Marley's "Three Little Birds".
Luna's "Woah, dude. Looks like pool's out for summer" line from "Linc or Swim" references Alice Cooper's "School's Out".
Luna once sung the line "Walk this way" in "Changing Baby", which comes from "Walk This Way" by Aerosmith.
Luna has two in "Hand-Me-Downer". When she gave Lincoln her broken guitar, she said "Here you go, bro. All it needs is love. Love is all it needs", referencing "All You Need Is Love" by The Beatles. When referring to a bike Luna said "'Had to do some work on it. But then it was ride Sally ride". This references Wilson Pickett's "Mustang Sally".
One reference that got past the censors was her reference to "Highway to Hell" by AC/DC. In "Butterfly Effect" Luna tells Lincoln "Check it, bro. I uploaded a song about our family going down the highway to—*computer noise* hello! I just got 50 more hits."
In "Chores and Peace", all the sisters get in on the song reference however it's Luna that led them. It's a reference to Edwin Starr's "War".
Luna: Chores, huh, what are they good for?
Everyone: Absolutely nothing! Say it again!
When she, Lincoln, and Clyde get arrested in "For Bros About To Rock" Luna says "Sorry bro. I fought the law and the law won", referencing "I Fought The Law" written by Sonny Curtis. In the same scene she says "I know it's only rock-n-roll, but I like it". That references "It's Only Rock 'N Roll (But I Like It)" by The Rolling Stones.
Luna's come back "Yeah, dream on" in "It's A Loud, Loud, Loud, Loud House" references Aerosmith's "Dream On".
Luna singing "Time for me to go solo" in "House Music" references "Time For Me To Fly" by REO Speedwagon.
When Luna begs to Lisa in "April Fools Rules" she says "Please, gimme shelter!", referencing The Rolling Stones' "Gimme Shelter". Later on, Luna says "She's a black magic woman, dude", referring to Luan, which references "Black Magic Woman" by Santana.
In "Cereal Offender" Luna says over the microphone "For those about to shop: I salute you!", referencing "For Those About To Rock (We Salute You)" by AC/DC.
In "Raw Deal" Luna tells Lincoln "The vending machine gave me an extra bag of chips! The best things in life are free, bro", which references Ray Henderson's "The Best Things In Life Are Free".
In "'L' for Love", Luna said "Dream on, Lunes, you're the owner of a lonely heart", referencing Yes' "Owner Of A Lonely Heart" as well as possibly "Dream On" by Aerosmith.
In "Tricked" Luna complimented Lucy, "Halloween is kinda crazy with a spooky little girl like you!" referencing 60s song "Spooky" by Classics IV
In "Future Tense", Luna screams "We don't need no education!" when her parents sign her up for classes at a community college. This references the song "Another Brick In The Wall (Part 2)" by Pink Floyd.
At the beginning of the episode, Lincoln (while dressed up as Ace Savvy) is doing the Moonwalk Dance on bed, complete with him yelling at the end just like the late Michael Jackson did before doing that in his Live Performances (albeit for the latter, twice in a row).
