I feel like videogame music can manipulate me in a number of ways.
1> I mean, basic of basic, game music helps immersion. Whether it's to communicate a tense scene, or background of a town that helps communicate culture or mood. I think the best example is
Treno's song in FFIX or
Wall Market music in FFVII. In many cases the music isn't memorable, but you know what, it doesn't have to be. In fact it might be even better that it doesn't, the music is invisible and just melts with the background.
Music in this instance isn't suppose to be the forefront, and thus a lot of these songs aren't listenable out of context. And that's the genius of it, honestly, making sound that deliberately makes sense on in that one area, it's unique and it's part of that experience- without it, it means less. And vice versa, an environment without their music feels like less of what it is.
Final Fantasy XII and Silent Hill is the best example I can think of.

Manipulating music or sound that breaks norms of the game. Here the music is very much important and noticeable, but it's done to deliver a point.
Take for example, Aerith's death and the
Jenova fight. How much more powerful is that fight
because Aerith's theme plays? And vice versa, The Aerith theme is memorable but I feel like it's easier to get emotionally attached because we have to fight through it. The same thing happens in FFXIII in the
town of Oerba, which plays the same music in battle as the field, which helps make the location one of the memorable in the game.
I think it's equally powerful when you take away music. Although it doesn't quite fit in this example because the entire game is like this, but the fact that there is
no music thoughout
Limbo only helps with the creepy factor. And makes all the sound effects that signal your impending deaths (many, many, many deaths) stand out more.

Then there's the emotional, so beautiful you want to stay longer, it makes you emotional or ready for action just by listening too music. You know exactly it is saying, even without the scene, and it stays with you.
I remember staying at the church in Crisis Core to hear
The Burdened. I have the same reaction to the Another World
overworld theme in Chrono Cross,
Liberi Fatali from FFVII, or even H
alo's theme.
It's strong, memorable, and I probably downloaded the song for my ipod and listen it a million times until my ears puke.

The last type is less how composer use music, and more on the player itself. It's the nostalgic factor. When a game because so ingrained into part of your childhood, just listening to it invokes the feelings that you use to feel.
It's basically become a sensory memory. The way people react to certain smells or visual queues, it makes you remember things. The
opening scene in FFVII and the music, looking back at it, isn't as impressive as other openings but there are very few songs that gives me chills like that one does. There are certain songs in FFVII and in Zelda OoT that aren't particularly impressive (I mean, it's Nobou they are ALL great but you know what I mean) but when you hear them you immediately react. And then it makes you really want to play the game again.
