My thoughts on this.....
There are NO written rules for music (and I mean none, there's nothing in stone anywhere about things like this)
Dev, look dude, you're not God, you never will be, you need to be more willing to learn things, be open to the fact that something you don't get, might actually make sense to someone
I have some personal experience with such things, I have looked at a simple photograph (posted below) and written a piece just by LOOKING at it, it's not like I had a score or was going off of something previous, I was just playing what I felt when I looked at it and that was it, voila
Annnnd....
Here's the piece I wrote, at 2 AM no less, while looking at it
SoundClick artist: William Daniel Kirkland - A steel string playing classical guitarist
So seriously, nobody is in any position to say that one form of inspiration is better than another (and I mean NO one)
EDIT: Bugger that picture's huge...
