..to get you up in the morning. In no particular order.
Sorairo Days, from Gurren Lagann
If you haven’t seen it, go do it. It is the definition of hot-blooded anime.
Colors by Flow, opening song for Code Geass: Lelouch of the Rebellion.
Never mind that Lelouch Lamperouge is the best Magnificent Bastard in all of anime: the first opening song is pure energy, and great for those days you dont want to get up.
FACE, by TRY FORCE: opening to Heat Guy J
I SAID HEY, BOY, LOOKING FOR YOUR SOUL?
Adesso Y Fortuna, by Sherry: opening to Record of the Lodoss War
This is a criminally forgotten series. This is the anime equivalent of D&D and MMOs, done over 20 years ago, and virtually every fantasy game pays unknowing homage to it. Adesso Y Fortuna is a great song to kick off a binge of leveling.
BOA-Duvet: opening to Serial Experiments Lain
Imagine your only musical experience in anime is bouncy 80s style synth pop. You see a new anime, buy the VHS, and hear this. You get religion.
The anime itself is intense, and it only seems fitting to pay homage to the God of the Wired by letting Lain end it, Part 2 coming soon.
