My favorite Chrono Trigger song is Delightful Spekkio.

I also like Fanfare 1 and Gato, but not much else. Burn Bobonaga is decent, too.

I like FF VI's soundtrack much more.

Just off the top of my head, I like Techo De Chocobo, Relm's theme (my two favorites), Blackjack, Looking for friends, Zozo, edgar-sabin, the veldt, spinach rag.

I like the FF VI battle theme. I like 1 and 4's more, though.
