So you're leaning back in your comfy theater chair, next to your significant other, munching on overpriced lobby snacks, when the [[ComingAttractions previews]] come on. The first opens with some dramatic InAWorld narration about the EarthThatWas...but wait a minute. That music sure sounds familiar. "[[RequiemForADream Requiem for]] [[LordOfTheRings a Tower]]", again? The next trailer is for some run-of-the-mill PG-rated EddieMurphy ToiletHumor kiddy comedy. It's "I Feel Good" by James Brown! Again!

This is a common movie trailer trope. Simply put, many editors of trailers find it easy to use famous songs to elicit a specific mood within a two- or three-minute duration.

See also StandardSnippet. RecycledTrailerMusic is a close sister trope.

!!Examples:
* Listen to enough music from companies like Two Steps From Hell, Audiomachine, EpicScore, and Globus, and you'll start recognizing a LOT of the songs used in previews, both on TV and on the big screen.
** America's Got Talent is particularly fond of using Two Steps From Hell, particularly Heart of Courage.
* As mentioned above, JamesBrown's "I Feel Good" is the go-to song for inane kids' comedies based around ToiletHumor and EddieMurphy [[ActingForTwo playing all the characters]]. In fact, its status as a cliché was [[LampshadeHanging lampshaded]] in ''Film/TropicThunder''.
* And for kid's comedies that are less gross and more heartwarming, "I'm Walking on Sunshine" by Katrina and the waves is a popular choice.
* As also mentioned above, "Requiem for a Tower" is pretty popular for overwrought Sci-Fi/Action epics. Hell, even ''TheDaVinciCode'' used it.
** For clarity, the song is called "Lux Aeterna" and was written (by Clint Mansell) as the main theme for ''Main/RequiemForADream''. It's become the default action/sci-fi/epic/drama/pretty-much-any-genre music for trailers, since it was used in the trailers for ''Film/TheLordOfTheRings''.
* "What's This!?" from ''WesternAnimation/NightmareBeforeChristmas'' has made DannyElfman enough royalties for him to live on all by itself.
* It's a little known fact, but U.S. law requires that a minimum of 75% of all RomanticComedy trailers every year use "Are You Gonna Be My Girl" by Jet. And of course, the answer to that question is inevitably [[StrictlyFormula yes]].
* Gary Jules' cover of Tears for Fears' "Mad World" is becoming popular for Horror/Action trailers during [[SoundtrackDissonance fast-paced montages of violence and/or desolation]], as evidenced by its use in commercials for ''GearsOfWar'' and ''TheCrazies''.
* Up until the mid-2000s, a handful of tracks ("Name of the Game", for example) by TheCrystalMethod and TheProdigy were very popular in ads for everything from energy drinks to action movies. The use of big beat has become a DeadHorseTrope in advertising now, and has contributed the [[GenreKiller death]] of classic, FatboySlim-style big beat.
* Blink-182's "All the Small Things" is a popular choice for [[DawsonCasting teen comedies starring actors in their late 20s]]. Also, any comedy where something is small (e.g., ''Film/AlvinAndTheChipmunks'').
* Saliva's "Click Click Boom" is there for the prospective trailer editor who wants an [[TotallyRadical X-Treme atmosphere]] for chugging Mountain Dew.
* From 1999 until a few years into the TurnOfTheMillennium, "All Star" by Smashmouth was in ''every'' ad for ''everything'' ever. Those ads included the trailers for the ''Franchise/{{Digimon}}'' movie, the ''InspectorGadget'' movie, and ''{{Shrek}}''.
* [[http://www.youtube.com/watch?v=WlAHZURxRjY "Song 2"]] [[{{Music/Blur}} by Blur]] - also a StandardSnippet in action scenes, particularly extreme sports.
* Want music for the trailer of your TV show? Is this week's episode particularly dramatic? [[Music/FlorenceAndTheMachine "You've Got the Love".]] Done.
** Also [[{{Adele}} "Set Fire to the Rain"]], especially on Lifetime.
* For a while around 2005-2006, any song by The Fray ("Over My Head", "How to Save a Life") was common in trailers for dramatic shows like ''GreysAnatomy''.
* "Firework" by Music/KatyPerry has been used in the trailers for both ''{{Prom}}'' and ''Soul Surfer''.
* When it first came out, "Tik Tok" by Music/{{Kesha}} was popular in trailers for kids movies.
* At least three movies have used the Music/DavidBowie[=/=]Music/{{Queen}} collaboration "Under Pressure" in their trailers -- ''{{Stepmom}}'' (also used in the film's opening sequence), ''The Girl Next Door'', and the ''[[Film/{{Arthur}} Arthur]]'' remake (that trailer also used Bowie's "Rebel Rebel"). Never mind that the pressure the song is discussing is that of dealing with a world gone mad, rather than raising stepkids or romantic travails.
* "Solsbury Hill" by Music/PeterGabriel seems to be the go-to song for "feel good movie" trailers. Odd, since it's a rather bitter song about Gabriel leaving Music/{{Genesis}}.
* KT Tunstall's "Suddenly I See" was used in ''TheDevilWearsPrada'', and ever since has been used in various trailers for movies, TV, and commercials, usually in scenes where women are empowered. It was even parodied by ''Best Week Ever'' in 2008, which played it with scenes of women working in sweatshops.
* Films with a comedic existential theme to them seem to favor "Once in a Lifetime" by Music/TalkingHeads.
* It seems now of days if you want some Epic, thematic music to go along with your Action / Sci-Fi trailer, just use a track from "[[Music/NineInchNails The Fragile]]". Most notably, the track ''Just Like You Imagined'' was used for the Trailer to Film/ThreeHundred
* Recently, Danny Cocke's "Sinister Intent" is getting some mileage. Being used in the ''Film/{{Dredd}}'' and ''VideoGame/XCOMEnemyUnknown'' trailers, the song is now appearing in promos for Season 3 of ''The Walking Dead''.
* Imagine Dragons' song "Radioactive" has started showing up in a great deal of advertisements, such as things for ''VideoGame/{{Defiance}}'', ''{{Graceland}}'', and other media.
* Since Inception popularised it, a lot of Movie trailers now use the BWONG noise. It's even popped up in a few soundtracks here and there.
* Music/SleighBells' "Crown on The Ground" --- among many other tracks of theirs --- seem to pop up in various movie trailers these days.
* EllieGoulding's "Explosions" was used as {{ITV}}'s soundtrack to their "Where Drama Lives" series of adverts, and even starting charting highly on the UK Singles Chart as a result.
