What is going on with the score? I can't find any infor of it.

Released or not?

Here are a few facts that I've gathered from the credits

1. It was never released.
2. Lorne Balfe was Technical Advisor :coughAdditionalMusicAnyonecough:
3. Brian's score from Fast 5 was tracked in.

Yes, not new info, but, I wasn't surprised that this didn't happen. Though I'm still hoping that someone might have a recording session/film mix out there.

Alright... Thank you.

It was discussed in the request thread: It's up to his company to release it or not and they're still sitting on it.
There's no way of telling if it will, ever.
I believe they would think about it as it gets closer when the movie hits the shelf for home release.
but that's a big "maybe" with no certainty or way of asking.

It's been asked on his official facebook page a million times and he always never knows himself.

“3. Brian's score from Fast 5 was tracked in.”

Too much?

Most of the thematic material was Brian's, Hybrid contributed a lot of the electronics ( Fast & Furious 6 | Hybrid Scores (http://www.hybridscores.com/aproject/fast-furious-6/) ) and then there was Vidal taking point. Now I'm not sure, but maybe the label is having difficulties with contracts or licensing, considering the amount of people involved...? Although that type of thing would generally be taken care of in contracts prior to involvement...
Either way, it's surprising that a film so successful, and whose past 3 entries have enjoyed score releases, should have none.

the label is having difficulties with contracts or licensing, considering the amount of people involved...?

No, Vidal and his label both haven't stated any licensing issues.
They just said they might release it "later".
They didn't say what's holding them or given a date for possibilities.

Most people suspect maybe when the movie released for DVD/BD home release.
