Since I don't write music for others, do you write a song with a certain artist in mind beforehand, or do you just see where it ends up and what they sound like performing it?

I'm merely curious, since well, like I said, all stuff that my fellow band-mates or me make stays within our group. And while I have done collaborations with other artists that was made by them and them alone. I just followed their guitar tabs, which is something entirely different than vocal lines.
