I spent more time deciphering this post than time choosing a the song.
Well I put FFVIII boss song in the last post (as reply to a comment.) so I'll put the battle theme from CHRONO TRIGGER this time:
Tell me how much emotions in there ^ The fight begins.
Well, it was the best work for its composer, and he was mentored & monitored by Square-Enix best known musician at the time so of course all Chrono Trigger sounds is amazing!
