The Justice Ray Part 1 [Blast Wind]

Nuclear Throne's theme is basically this without the electricity but has the awesomeness and nostalgia.

Xexex Princess Irene Theme

This sounds the metal band Rhapsody.

Holly shit this is just so Yngwee...

Parts I and II both contain a feeling of climactic sadness... however they each have a secondary element exclusive to them.

Part I has a hint of "hopeful inspiration".

Part II has an aura of "vengeful rage".

When I heard this theme in Blast Wind I definitely knew it sounded familiar.

DARK VOID - OVERDIMENSION - MARK'S & CO. INFINITY EIGHT

I love this part, it's sad, reminds me of the first time my best friend, my brother and I completed Thunderforce 3. EDIT: Because it sounds like reflective music played during the final level of a completely kick-arse shooter.

This part is pretty good, but Part 2 is definitely still my favorite. Thunder Force V had the best bosses of the series and the final level was the most intense of any game I've ever played. :-)
