I watched the Jonathan Ross interview and the contrast between NF and ST is stark.
i.e. When Jonathan Ross starts talking about how the cap reminded him of what his wife wears into the shower, and later observing another "what a grandmother might wear." That's clearly "N" and "S" looks at Ross like wtf?
Eminem states very clearly how he writes music. It's very mechanical using patterns in words...vs. choosing words carefully to communicate a specific thought. In other words, what sounds better to the ear is more important to the topical vs. actual content.
The intensity of his gaze is very common among ISTP's. But wouldn't go so far as to say that's his type. In that there's a ton that's unknown about him.
i.e. We know that he likes Comic books, and wanted to have a comic book store. We know that he dropped out of school, although very talented...definately not the brightest bulb in the forest.
We also know that running is his choice for getting exercise.
So I'm sure of "I" in that it's biographically well documented, sure of "S"...reasonably positive of "T" in just observing his spoken word choices as to P or J? Not sure.
