What turns a movie into a masterpiece? A spontaneous song-and/or-dance number, of course! (This list excludes all musicals, animated films, and dance-based movies such as Dirty Dancing and Footloose.) This definitive ranking of the top 16 musicals numbers comes from none other than my own brain and taste in movies.

16. We Are Not Alone-The Breakfast Club (1985)

I couldn't tell you why this scene is even in the movie at all, other than to show that if you smoked marijuana in the 1980s, you became really good at air guitar (I'm looking at you, Emilio Estevez). It is an iconic scene, and if nothing else, this is probably the most 80s thing you'll see all day.

15. Old Time Rock and Roll-Risky Business (1983)

The Tom Cruise underwear outfit has become a staple Halloween costume for college girls. Why? I don't know. The movie is about a high school student being left alone while his parents are on vacation, hiring a prostitute, and somehow ending up running a brothel and leaving Mom and Dad none-the-wiser when they return. This scene where he dances around in his tighty-whities to kick-off his alone time is quite honestly the highlight of the movie.

14. Dance-Napoleon Dynamite (2004)

I'm not a huge fan of Napoleon Dynamite myself, but the dance scene at the end makes up for it a little. There's just something about Jon Heder dancing by himself in snow boots to disco music for two and a half minutes.

13. Johnny B. Goode-Back to the Future (1985)

Besides tricking a bunch of people into thinking a skinny little white guy came up with one of the most famous guitar riffs of the 1950s, this scene definitely deserves a spot on our list. The greatness of this number comes from Michael J. Fox getting totally into it, even though he's not actually singing or playing the guitar.

12. Thriller-13 Going On 30 (2004)

In 13 Going On 30, Jennifer Garner's character Jenna magically ages 17 years overnight after wishing to be older at her 13th birthday party. When her boss's work fundraiser is about to die, she asks the DJ to play the biggest hit from her youth (which for her was like a day ago) and saves the day. Another great musical scene from this same movie is when Jenna is having a sleepover with the other thirteen-year-old girls in her apartment building and introduces them to Pat Benatar (https://www.youtube.com/watch?v=MlkBb0nibFE)

11. Sweet Child O' Mine-Step Brothers (2008)

In typical Judd Apatow style, a goofy scene that has absolutely nothing to do with the advancement of the plot is the one that makes us laugh the most. "I'm Derek, and I can sing high like this. And I can sing high."

10. Try A Little Tenderness-Pretty in Pink (1986)

Good old John Hughes sure knows how to give us epic musical number for no reason. Every friend group has a Duckie and can definitely relate to someone goofing around, lip synching and dancing just to get attention (wait, am I the Duckie of my friends?) Maybe Jon Cryer should have shown off more of these sweet moves in Two and a Half Men.

9. You Always Hurt The One You Love- Blue Valentine (2010)

Blue Valentine explores the relationship of a struggling young couple, but this scene shows them when they are first falling for each other. Ryan Gosling, we don't care if you have to sing goofy. You can sing and play us the ukulele any day.

8. You Make My Dreams-(500) Days of Summer (2009)

Since (500) Days of Summer is not exactly a feel-good movie, it's nice to have a break from the sadness and watch Joseph Gordon-Levitt dance down the street to Hall & Oates with fifty other people. This is the way we all feel when we realize we're in love, we just don't have Harrison Ford giving us a wink of approval.

7. Chopsticks-Big (1988)

What's a movie list without Tom Hanks? "The Piano Scene" made every kid (and adult) want to go play Chopsticks on the big keyboard at FAO Schwarz. The store gained a lot of popularity in coming years as people did exactly that. Unfortunately the famous toy store is now closed, so if you never got live out your childhood dream, it looks like you'll have to buy your own giant keyboard.

6. Afternoon Delight-Anchorman (2004)

In another great Judd Apatow scene unrelated to the plot, Ron Burgundy (Will Ferrell) explains the feeling of love to the other members of Channel 4 News Team. The thing that makes Afternoon Delight so unique is that it's placed in the middle of the guys' conversation and then dismissed like it never even happened.

5. Puttin' On The Ritz-Young Frankenstein (1974)

Perhaps the iconic scene that inspired Mel Brooks to write the Tony-nominated musical of the same name, the song-and-dance between Gene Wilder and Everybody Loves Raymond star Peter Boyle, had audiences rolling in the aisles. The creature's mastery of the English language and Wilder's mastery of basically everything come together to create the perfect scene.

4. The Banana Boat Song-Beetle Juice (1988)

The whole idea that the ghosts are trying to scare away the people living in their house with a dance number is pretty hilarious. Catherine O'Hara's face as she is being possessed and forced to dance to Harry Belafonte makes it all the more humorous.

3. Can't Take My Eyes Off Of You-10 Things I Hate About You (1999)

Based on Shakespeare's The Taming of The Shrew, 10 Things I Hate About You is basically about this guy getting an impossible girl to go to the dance with him so his buddy can take her sister to the dance. Honestly, how could she say no when Heath Ledger is singing a Frankie Valli song to her?

2. Bohemian Rhapsody-Wayne's World (1992)

Not only is this scene a great way to introduce the feel of the movie, but it is also shows off the scenery where the movie takes place. Is it a necessary scene? No. But it's a far more entertaining way to get the characters from one place to another than by simply cutting to the next scene. Is it an iconic scene? Yes. Like you and your friends have never blasted this Queen hit and sang every word.

1. Twist and Shout-Ferris Bueller's Day Off (1986)

Perhaps the clichéed choice for number one, this scene earns its spot with not only entertainment, but also fun facts. Considering the fact that the filming of this scene did disrupt an actual Chicago parade, some of the extras that appear (like the dancing construction worker) were simply people the cameras happened to catch enjoying the music.(http://www.imdb.com/title/tt0091042/trivia) Matthew Broderick was also supposed to do much more dancing, but hurt himself filming another scene, and this scene could not be filmed another day. Imagine how much more epic it would have been with his sweet moves.
