Dragon Quest/Awesome Music

Dragon Quest I

 * The Overture March (also known as the Dragon Quest Medley or just Overture). (Symphonic). Behold, a song instantly recognizable instantly to the entire country of Japan for the past 25 years, it has been remixed literally thousands of times and prefaces every Dragon Quest game.
 * King Dragon, the final boss theme. (DQ9 Symphonic version)
 * The overworld theme of the first game, has been included in many games, not just the remakes of the original DQ1.
 * SNES version
 * Gameboy Color version
 * Itadaki Street's Arrangement

Dragon Quest II

 * "A Lonely Youth", the overworld theme that plays when you start the game with the Hero going solo for the first part of the game.
 * GBC Version
 * "The True Evil", The final battle theme with.
 * It's even more awesome in Dragon Quest IX!

Dragon Quest III

 * The Overture remix, that only plays after we see the Hero prepare and proceed on his journey, or more specifically (in the GBC remake)
 * The Overworld theme, appropriately named "Adventure", gives players a foreshadowing of epic the journey is going to be.
 * SNES Version
 * Orchestrated Version
 * Heavenly Flight (Symphonic). You can take your airships, I'll take riding on the back of a giant sentient bird deity any day.
 * Battle Theme
 * Boogie-Woogie, the lobby theme for the Monster Arena and the Pachisi Board minigames. Sadly, it was not in the original NES game.
 * GBC version
 * Itadaki Street version
 * Hero's Challenge -- the first time a Dragon Quest final boss has had two themes -- plays when you finally use the Sphere of Light to weaken Zoma so he can be defeated for the first time in history. (Symphonic from DQ 9)

Dragon Quest IV

 * The final Overworld Theme that plays when the entire playable cast has finally joined together, Wagon Wheel's March, is quite heroic and sets the tone of that point in the game well.
 * Its Itadaki Street DS arrangement is even more epic.
 * Casino Rag, the gambling area for the game.
 * Fortune/Itadaki Street DS arrangement
 * In the original version, the credits theme was pretty good, but in the remake they turn it into an all out Fanfare.
 * Evil One, which you got to hear twice in the game (Against Estark and agains the final boss). It would later go on to become Estark's Leitmotif.
 * The DS remake's version is also awesome.

Dragon Quest V

 * The Overture makes its appearance here, but another special note of just when it appears is required: It's only after we, the crushing silence broken by   that the overture begins. This is how you add atmosphere to a game.
 * As is usual for the series, the Overworld theme, in this case called Toward the Horizon, is excellent.
 * "Racing Slimes!"
 * Violent Enemies, the normal battle theme, is one of the best in the series (also its DS version.) In addition, the Boss Theme isn't too shabby either. To top if off, there's the Symphonic version of both these themes.

Dragon Quest VI

 * Through the Fields - Overworld theme.
 * Another World - its Mirror World counterpart, is slower, more solemn, perfect for a dream world.
 * Courageous Fight - the standard battle theme
 * Brave Fight - used only once when facing against Mudo/Murdaw.

Dragon Quest VII

 * World of the Strong - An epic boss theme.
 * Symphonic version

Dragon Quest VIII

 * An Orchestrated Remix of the Overture, where the Dragon Quest dev team and Level 5 show off their fancy new engine to the tune of an Orchestrated remix of the song all while a pair of birds fly for miles using the in game engine and no load times. Epic. Just Epic.
 * theme, Great Battle in the Vast Sky. More subdued than the typical last battle, but only because  may possibly have pulled off the biggest Kick the Dog moment in Dragon Quest History. It also contains   from Dragon Quest III mixed in --

Dragon Quest IX

 * Everything. Just everything. Featuring remixes of nearly the entire Dragon Quest OST library, all done in glorious symphonic remixes. They went all out for the series' glorious return to the west, and it shows.
 * Observe the Dragon Quest 9 Overture Remix, now with a buildup and an orchestra playing it (the first time they have skipped the chiptunes and went straight for the big band).
 * Some examples of the remixes: Zoma (DQ3), Rhapthorne (DQ8), Dragon Lord (DQ1), Estark (DQ4).
 * And the final battle theme, which has the Overture mixed in with it.
