For me, it would have to be "the fight will be your own". Everytime i hear it it just screams out optimus to me.  
Top 5:
1-"the fight will be you own"
2-"no prisoners, only trophies"
3-"there is no plan"
4-"its our fight"
5-"i promise"

 

I don't know the name of it, but I love the sad, downbeaten reprise of "Arrival To Earth" when the Autobots are going to leave Earth. Truly heartbreaking.

 

Right now, I'm going with There is no Plan. I know it's a rehash of Arrival, but it's just a stunning piece.

 

There is no plan, or No prisoners.

 

thats another thing i saw in "the fight will be your own".

 

"In Time You'll See" and "No Prisoners, Only Trophies." Both of them really brought out emotion to me.

 

It's called "There Is No Plan". But yeah, I loved that one too.

Favorites from all three scores:
The first film
*Arrival to Earth
*The AllSpark
*Optimus
*Scorponok
*Frenzy
*No Sacrifice, No Victory
*Decepticons

ROTF
*NEST
*Forest Battle
*I Claim Your Sun
*Heed Our Warning
*Infinte White
*Matrix of Leadership

DOTM
*There Is No Plan
*Battle
*Sentinel Prime

I haven't listened to the entire DOTM score yet, but those three are my favorites so far.

 

Sentinel Prime's theme.

Battle
Its our Fight
Our Final Hope
Sentinel Prime
The World Needs You Now
There is no Plan

 

we have something in common  

 

Guess im alone then o_o

 

Battle and There is no plan

 

It's our fight.

 

While I love the battle music, I think for me the fave is track 'Sentinel Prime.'

It sounds like a song of remembrance, but tinged with sadness.

 

TF1:

• Autobots
• Skorponok
• Optimus

ROTF:

• Forrest Battle
• Nest

DOTM:

• Battle
• Sentinel Prime
• This is Our Fight Now

I hope we get a special edition of all three discs with a DVD that shows some behind the scenes of recording and mixing with Jablonsky... in a collectors' case. Hey, I can dream.  

 

"Shockwave's Revenge" was the miost awesome thing ever.
The definitve theme for SHOCKWAAAVE.

 

From DOTM
"Sentinel Prime"
"Battle"
Take the care for me. The "Battle" amplifies the highway scene to an unknown level of awesomeness.

And "Sentinel Prime" sets the perfect tone for Optimus' mentor. Emotional reunion between the two primes.

 

The fact that he mixed up "Arrival to Earth" and "Bumblebee Captured" from the first movie for "There Is No Plan" really got to me, so I'd say that one is my favorite. I love the whole score but that, "No Prisoners, Only Trophies" and "Sentinel Prime" are my top three.

I guess out of all three scores, the original is still the best. I mean, it's hard to hold a candle to "Bumblebee" and "Arrival to Earth." It's just ... epic. I love Jablonsky's style.

 

From all three movies, its definitely Skorponok. I wish it had been in DOTM
