3. "WE ARE Xros Heart! (WE ARE クロスハート!)" by Kouji Wada — from Digimon Xros Wars
This is a song that oftentimes can be heard throughout all of Xros Wars seasons. I love how catchy evolution slash fight music is for Digimon, and We Are Xros Heart! is a fine example of that. It's a rather simple but nevertheless a catchy song, possibly thanks to the everlasting voice of the late Kouji Wada.

2. "Break the Chain" by Takayoshi Tanimoto — from Digimon Adventure:
Continuation of the upbeat catchy evolution slash fight music listing brings us Break the Chain from the newest Digimon anime, a reboot of the original Adventure series. While this new series may have some serious lackings, the soundtrack is amazing, and its leader is definitely Break the Chain, a song that never left my ears once I heard it.

1. Hirogaru Fuan — from Digimon Adventure [1999]
The first and the foremost of all Digimon anime. The original Adventure series. Digimon Adventure from 1999 is the winner among all contestants of great Digimon soundtracks. There is just nothing quite like the solo songs and the instrumentals Adventure has. Of course, I couldn't not pick a track from this series as my favourite. Adventure instrumentals were perfectly arranged for the show, and Hirogaru Fuan is not excluded. I definitely recommend giving it a listen.
