Probably Gilgamesh/Clash on the big bridge from FFVA. One of few background music I can appreciate and the battle itself is well done and entertaining.
Yes, growing up we've shopped at the thrift store across the street all the time. Pretty neat stuff in there if you don't mind crowded places and dust. I do still sometimes if I'm on a budget.
I honestly have never been a fan, but that's probably because my little brother was a psychopath (okay, still is), and gave me a bad experience with them LOL.
