https://www.youtube.com/watch?v=xz_3trp9RlE&list=PL49207A67C68DE4EBDragon Warrior was one of the first (the first?) turn-based RPG to come to the NES. Despite its immense success - they are up to, what, 10? - I think the game was pretty terrible and difficult. Equally terrible was the soundtrack. The sounds were average for the time but even Final Fantasy had it much better. Here is my review (please note that I skip redundant tracks and group similar ones together)
2- Battle Theme With Intro
Including the sound of the intro was well thought-of. Otherwise, the track is very boring and repetitive. The composer was either very limited in his choice of arrangements of he made it at the last minute. It doesn't even sound like a battle theme.
3- Castle Theme
This track was a little better. Although the loop is very short, at least it made efforts to sound a little "regal." The main track tries to imitate trumpets to show some royalty, which the 8-bit track in the background adds a nice touch.
4-11 - Cave Theme
This is basically the same track, which simply gets slower and creepier as you go deeper into a cave (you basically hear all of them inside the final dungeon). Despite being so short, the loop nevertheless gets more and more interesting as you go deeper and deeper under the ground. The 8-bit track adds the right touch of drama.
12- Cursed Theme
Should you be unfortunate enough to try to wear a cursed equipment. The sound was used over and over in subsequent Dragon Warriors, showing that it is highly appropriate. Indeed, it really feels that something is wrong with what you just put on...
13- Dragon Lord Theme
The final boss battle. It was well thought-of for the period - Final Fantasy only had a single battle theme. The arrangements are more tolerable than the regular battle theme, and the background track has a very epic sound to it for the time.
14- Ending Theme
Self-explanatory. While the arrangements do flow well, and are far more complex than any other in the game, I never cared for ending themes.
15- Enemy Defeated
Self-explanatory. It's very short and doesn't create a huge fanfare like FF, which is good. Those 2 seconds are enough to show you that you won, and that's plenty
16- Fairy Flute
When you try to put Caitlin's Golem to
sleep. This actually is one of the most realistic sounding flutes of the 8-bit era. Even Super Mario Bros. 3 didn't play it as well. Another short, very well-done track.
17- Gained Level
Another extra thing DW has and FF lacks. It's always good to have some sort of sound signaling that your strength has increased, and it doesn't need to be very long.
19- Inn Theme
It sound more like a recovery theme rather than a
sleeping theme. Dragon Warrior II had it better in that respect.
20- Overworld Theme
Another track that suffers from its short loop. Even though it has some epicness to it, the main flute track is just too primitive and high-pitch to be interesting. And the background track just plays the same few notes over and over again and is terribly annoying.
21- Party Slained
I like my dying music short, like this one. The arrangements sound dramatic enough to show that "thou hast die." It even has a medieval touch to it; it sounds like a harpsichord.
22- Rainbow Drop
When you create your bridge to go to the Dragon Lord's Castle. The "harp" sound even better when you look at the psychedelic colors on-screen as the bridge appears. It was done well.
23- Silver Harp
An optional instrument you play to have enemies appear. That too was done well; it actually sounds like a harp (well, a lyre to be exact.)
24- Throne Room
Inside Tantagel. It's more elaborate than the castle theme, thankfully. The "trumpets" also are more enjoyable and their arrangements in the "prolonged" loop are good as well.
25- Title Theme
You will hear the first part in subsequent DW. It was as good as it got in 1986. The rest of the track is just plain annoying with its primitive arrangements, whose notes are all stuck together.
26- Village Theme
In any village outside of Tantagel. It sounds quiet and welcoming, like most RPG village themes. The 8-bit track in the background can get annoying, but the main track is loud enough for you to forget about it.
Final diagnosis: unless you played the original game back when it was released, I don't believe you will enjoy neither the game nor the soundtrack. It hasn't aged well, it loops too quickly and its arrangements are too primitive.
