I think a couple people mentioned similar things, but I tend to have an idea and often like to set fitting music to it after the fact.
I suppose a good example of this is the forum RP I have going right now with Gran - Running of the Piglets. I knew I wanted to do a goofy little thing about a baby behemoth wandering around getting into trouble. Whenever I'm in an aimless, peppy sort of mood, I often found myself humming Nina's theme from BoF3 (in no small part because it's simple and quite catchy), so I included it in the OOC preface for others to enjoy.
So, I suppose it's less that the music shapes the roleplay, but more that it adds... focus? Direction? I know that when I really want Chachan to do stuff that's lighthearted and goofy, I'll pull up Baby Elephant Walk. And even before coming to RPC, I liked finding appropriate music when choreographing a fight scene in a story. Odd enough, I've had ideas - and attributed music - for fights that haven't even happened yet.
... Is that weird?
