For me it would be
From Final Fantasy IV
1. Tenderness in the air
2. Music box
3. Red Wings
4. The Prologue
5. Melody of lute
6. Chocobo Chocobo
7. The Epilogue
From Final Fantasy V
1. Tenderness in the air
2. Music box
From Final Fantasy VI
ALL OF IT, but the music that plays at the opera is my ABSOLUTE FAVORITE
From Final Fantasy VII
1. The music thats playing on the World map
2. Sephiroth theme
3. The death of Aeris
Also Lunar 1 n 2, The legend of zelda theme , The mario brothers theme , Xenogears, xenosaga, Chrono Trigger and Chrono Cross, Secret of Mana, and Cowboy forgot about Suikoden III. Also games like Medal of honor and Call of duty has great music worth checking out.
