Look, I found the "original ost" with 22 tracks but this one seems missing..... obviously right? Why would anyone want a heroic song that happens in an important plot point when one can stuff the ost with filler instead?

The track I seek starts here at 5:00
YouTube - Digimon Data Squad Folge 29 (2/3) (http://www.youtube.com/watch?v=C2xZIs_ZWcc&feature=related)
And here the same in the Japanese version, here we get the song right away
YouTube - Digimon Savers 29 part 3 (http://www.youtube.com/watch?v=woZljOKJRis)

Anyone know where I could get it?

nevermind found it
YouTube - Savers - Big Time Changes (http://www.youtube.com/watch?v=l4rzHCvD2cM&fmt=18)

It's intense >:O I found Data Squad slightly darker than the rest because one of the bad guy's were exploiting a death :/

I found the Latin Opera song kind of cool too.

Latin Opera song???

Well anyways thanks for the reply. Yeah both Tamers and Digimon Data Squad are kinda darker hence I like them more. I like 02 more than the original Adventure, but even if Adventure was kinda KIDDY, I enjoyed it, but Frontier? I HATE Frontier! And looking at Xros Wars..... I got a bad feeling about it, but I'm yet to properly watch it.
