Could be comfort zone syndrome. (covers just liking certain songs and those keys,,,,or for not learning all the a to z's of scales and chords)

Could be tone color addiction.

Could be Vocal reasons, and the habit of starting off in certain keys to which to find a melody, or once having a melody, to go to chords of usual and make it fit,,,,or even change the melody, (which might be a mistake if not as good as the one there, just because of not being able to hit the previous high note, and not wanting to move the key down).

Sometimes, blues riffs, (for piano, as I know better about them), can be honed over the years by staying in one key, as it then becomes so natural to play whatever the heart desires. I started to play Jazz and blues riff in C, and since can play them in my sleep. If on keys, and the song calls for some heavy duty riffs, I'll pitch the key to have it be as if it's in C. (is that wrong?)

I can adapt for other keys, of course like G, for that kind of playing, but it's not as natural. I'd rather not think when expressing a feeling or mood.

I have songs of various genres in all keys. It's the tone color that attracts me most for the mood of the song that either comes to me, or I somehow choose to compose. (maybe it's the same thing). But I noticed on the two films scored, I just found a note or chord that seemed to fit the scene's mood,,,or sometimes. even the opposite of the obvious mood. (Contrasts work too, and finding the key for them is,,,,dare I say, key>,, oh man.
