I found 1 interview with Q where Thriller 25 was mentioned:
Quincy Jones' 'Thriller' Memories
As the landmark Michael Jackson album turns 25, its legendary producer tells us what it means to him, what happened at his recent get-together with the King of Pop, and whether he's got more music to make (Snoop Dogg and Joe Pesci (?!) think so)
Quincy Jones could use a day off. Twenty-five years after producing Michael Jackson's Thriller, at an age when some might be settling into a peaceful retirement, the 74-year-old music-biz legend stays busy crisscrossing the globe for various philanthropic projects. ''I'm so tired of these planes, man!'' Jones kids. ''I'm going to go to Brazil tomorrow. It's ridiculous.'' During a rare free moment at his Bel Air, Calif., home, Jones chatted with EW.com about this month's deluxe Thriller anniversary edition, his most recent visit with Michael Jackson, and whether the music industry is too far gone to be saved.
ENTERTAINMENT WEEKLY: How do you feel when you look back at Thriller, 25 years later?
QUINCY JONES: I can't believe it's that long ago. When I go to Shanghai or Cairo or wherever, it's shocking to see that they're still playing it all over the world 25 years later. It's an honor to me.
When you were in the studio recording that music, did you ever imagine it would be that timeless?
You don't think about that kind of stuff when you make records. You want it to be played next week! [Laughs] It's astounding. I picked one of the most incredible teams in the world, the guys that I worked with — [songwriter] Rod Temperton and [engineer] Bruce Swedien and [keyboardist] Greg Phillinganes and [horns/strings arranger] Jerry Hey — it was a divine situation. Everybody had this incredible respect and love and affection for each other. A team that is real honest with each other, that's the key. Because there's nothing in the world like getting a group of guys [like this] around.... I've seen a lot of people [whose] friends and cousins tell them everything they do is perfect. That's a big mistake.
Have you listened to the whole Thriller album start to finish in one sitting recently?
God, no. I haven't done that in 20 years.
Why not?
I have it in my system in my home, but I'm not going to sit there attentively listening to every song. We had a lot of music out in the '80s and the '70s. So it's never been a situation where I just sit down. Maybe I will one day, when I get time. Just sit down and relax and count the blessings, really. Because that's what they are.... Michael came by here the other day.
What was that visit like?
It was great. We just hung out and talked. It was nice to see him.
He came with [attorney] Peter Lopez. I hadn't seen him in a long time.
What kind of things did you talk about?
He told me that they were doing some remixes [of songs from Thriller] and so forth. Somebody sent it to me, and they're fantastic. Akon worked on one, will.i.am did one. They were beautiful.

It is possible that MJ brought Lopez with him to see Q and draw some sort of agreement regarding remixes etc. Q doesn't sound angry at all in this interview that he wasn't given choice to do re-edit or remix Thriller 25.
