Pursuit - Gotta Corner the Culprit (Variation) (OST Mix) - Apollo Justice: Ace Attorney 

The first three games have their Variations included on the OST, as well as Dual Destinies and Spirit of Justice. Apollo Justice is the odd one out, at least in the mainline series. Thanks for your comment!

It might be because it’s only used like twice. It’s kind of a shame though, I really like the start of this

It could be that the other variations added some more instruments in the background while this one and the investigations ones only changed the beginning

Seems in investigations collection they're called "no intro" for those tracks. Regarding missing pursuits, no variations exist in VS, TGAAC technically has one but it's basically just the normal track with the intro cut and only plays a single time. T&T doesn't have the Cornered 2004 variation in the OST but the way it's handled is incredibly strange. In the GBA ost, there's instead a track which is a combination of the usual track and the variation, for whatever reason. Sound Box (Wiiware) just uses the normal track directly without adding any part of the variation. I believe Gyakuten Saiban Jiten uses the GBA arrangement of the *variation* with DS instruments (like all T&T tracks there), though I can't remember what it's called in the sound test.

It's easy to miss, but this track actually plays twice in-game! Once in Turnabout Corner, during an argument about Stickler's dropped phone, and once in Serenade when Machi is accused of being an accomplice.

Please check the channel description.

@@in1tiate fucking got me

This really should have played during Apollo’s big moment

@@snakeshifter02 Fortunately, there is a video for that. Just a video, though. Not an in-game option, as far as I'm aware. Ah well.
