Let me give you an actual quote from this commentary:

"I was always a fan of Biggie. I was more into [??] but when Biggie died I was like, this is just big more, you know what I mean, got more into Biggie, know what I mean, Biggie's was very talented, and like, actually, I figured, like, if he wouldn't have, like, passed away he woulda did that video on his own and I wouldn't, like, never did the video, so it was like, kinda like a blessing, you know what I mean, so like, of course I like Biggie, you know what I mean, 'cause like, he had a influence."

I love it. He's basically saying, "it was good that he died so I could do this video."

Oh, and I counted. He says "You know what I mean" 23 times during this 5 minute commentary (and "you know what I'm saying" 5 times).

The veteran actor talks about how he rehearsed his routine for the video in only five days and shot the actual video in one day. He accepted the job because he liked the song and wanted to do a dance number before he got too old. There is a good does of Walken's trademark droll humor.
