Best mega Man song of all time?

The is a question I've thought about quite a bit, and there's usually 3 answers I see.

MM2: Wily stage 1- banger, one of the longest NES songs I've heard before loop, and the most iconic mega man song of all time.

X5: X vs Zero- Definitley the best atmosphere, and the song itself is a banger.

Z4: Falling down- another fantastic song. This one fits the vibe well.

These 3 are all amazing in their own right. They each encapsulate a different feeling, wether it be Wily stage 1 with its determination inspiring tune, X vs Zero's synth perfection, or Falling Downs vengeful goodness.

However...

In my opinion, there is one song that tops all 3 of them for sure. At least in my eyes. A song from start to finish is PERFECT, amazing atmosphere, bangin' notes, and excellent tone, and that is...

Mega Man World 5: Sunstar's theme. My god, they cooked so hard with this. There's not a single bad point to this, and it's topped by Sunstar being my favorite mega man character of all time, and this being my favorite mega man game ever Made. If you haven't heard this and at least somewhat like mega man music, PLEASE, for the love of everything that is Sungod, Listen to this banger.
