I love the Final Fantasy 13 series soundtracks. And I played the Final Fantasy 15 demo. From what I heard, I'm expecting that the soundtracks are going to be pretty good. :)
undertale has a great soundtrack. and oh, check out the touhou series (the main game series Toby Fox was inspired to make undertale). great soundtrack. there's also the legend of zelda, final fantasy, kingdom hearts, and the bravely default series. i know there's a lot more games i've enjoyed listening the music to, but this is all of them i could think of! :3
Fran bow-smell is pretty good to me it is short though about 1 minute https://www.youtube.com/watch?v=cy3hWT6y5XY Also Nisemonogatari -Bird of Death https://www.youtube.com/watch?v=lt06Ll6L9cw
I really like the Devil May Cry soundtrack (The original ones, haven't played the remake), though I like the soundtrack from Devil May Cry 3 best. Or maybe I just like Metal ^_^'
