When did assembling styles out of other already created styles (by other people) become 'creating our own styles'?

If I did this with an SMF, it would be 'editing' a commercial SMF. Since when did doing the same thing to a style become 'creation'?!

I know that even doing this is rare amongst arranger players, but I'm sure that someone that makes styles from scratch is sitting around going 'he just took some of my work, and some of someone else's, and now he's calling it CREATING a style?? '

Perhaps we ought to start calling it 'editing' our own styles, just to distinguish between those that actually DO create their own styles, and those that edit other's..?

I certainly wouldn't want to claim that an edited commercial SMF (or any third party one), no matter HOW much better I make it, is 'created' by me...
