I stay away from lyrics, period! I tend to let the music tell the story and in a way it does/must or we wouldn't have what are called instrumentals.
And believe it or not sometimes the music by itself tells a different story as opposed to when an image is attached to it.
If you watch tv/film, you'll see that the music within them has a greater effect and this is true when you get soundtracks though you often get them after having seen the film (or played the game, they have STs, too).
I was listening to the Mass Effect 3 OST on Youtube and could practically imagine where I was and what was going on in the game (yes, I played it alot) I knew if I was in a firefight or just exploring places because when fights were coming, the music would tense up and stay tense during the fights and die down when they were over.
However, the score itself can be deceiving as you may hear tense music in non-tense moments or relaxing music in tense moments.
Face-Off, comes to mind. [SPOILER ALERT: The scene where Troy (who looks like Archer) is shooting up Archer's (who looks like Troy) house (with Sasha) and the boy Adam is put on the bed listening to Over The Rainbow (superimposed to the audience while the action's happening in slow-mo)[/SPOILER]
Couldn't find the scene, but those that remember it know what I'm talking about
Clearly, this provided irony while that the same time, we see the onus on keeping Adam safe! I thought it was an extremely well-done sequence, but most certainly music and contrast played a huge part!
But yeah, music comes easier to me; so, I work with that and let someone else handle the lyrics.
In terms of the order I use to come up with music - specifically, arrangements, I go after everything else under and around the melody and then tweak that so both components are in agreement and/or deliberately impose minor disagreements coming to an agreement later.
This of course, gets into the theoretical portion with the main issue being consonance (agreement) and dissonance (disagreement) aka tension and resolution/resolve/release) which is music is about as are stories of any form and music is like a story which everyone seems to agree with.
Just the same, the difference is not what is being told, but
how and what devices are being used and how are they being used to convey the story.
