Oh I like this question!
Back when I first played FF XII as a 15-years old I really loved the soundtrack. Listening to it again now when I’m older I find it to be one of Hitoshi Sakimoto’s (who I’m otherwise a fan of) weaker soundtracks. His stronger ones in my opinion are Vagrant story, FF-tactics series and his work on the Odin Sphere osts, I really loved the soundtrack of Crimson Shroud too!
Sakimoto has a nice mix of memorable melodies and “flowy”, mood-setting compositions, there wasn’t as many memorable songs in FFXII so that’s why I consider it weak for being him. That said tho, I still really love the boss battle theme, Ozmone plain, the empire’s theme, the opening movie music and the credit roll-music to this day though!
