ACシリーズ20周年を記念して発売される「ARMORED CORE ORIGINAL SOUNDTRACK 20th ANNIVERSARY BOX」発売イベントで行われた、シリーズ楽曲全てのBGMを対象にした人気投票では2位のThinkerとは僅差で上回り、見事1位を獲得した。星野氏曰く「思い残すことがないというぐらいやりきった曲」というくらい会心の一曲だったようだ。また、該当サントラで「Day After Day (20th Anniversary Edit)」というアレンジバージョンが収録される。
Don’t forget a hole in the wall.
I’m like ghost to turn in on the load.
Day after day, I stay around on far away.
Day after I‘ve got it.
I’m going to stand on the floor.
By the way, I found a flower a little way away.
Oh, Way away.
To give surrender, my soul is wandering.
To back on safe ground I’m calling on far away.
How far away?
Don’t forget a hole in the wall.
I’m like ghost to turn in on the load.
Day after day, I stay around far away.
Day after I‘ve got it.
I’m going to stand on the floor.
By the way, I found a flower a little way away.
Day after day things are rolling on.
Day after day things are rolling on.
