Favorite anime opening themes?

[Naniyue]

 1.  Robotech

 2.  Starblazers/Yamato

 3.  Lodoss (OVA)

 4.  Cowboy Bebop

 5.  Area 88 (TV)

 That's it off the top of my head, anyway.  Yours?

[majors]

Escaflowne - "Yakusoku wa Iranai"
DNA? - "Blurry Eyes"
Rurouni Kenshin (3rd season ending) - "Heart of Sword"
Evangelion- "Cruel Angel's Thesis"
DBZ - "Head-Cha-La" <- I think this is on everyone's list

Bubblegum Crisis - anything! all the tunes are bangers.

 1.  Robotech

I get a wave of excitement, spine-tingling chills, and nostalgic euphoria when I hear the Robotech theme.

Nadesico! 

Lodoss Chronicles of the Heroic Knight opening is great.  They probably spent most of the money on this opening though:

The Ossan Newbie Adventurer, Trained to Death by the Most Powerful Party, Became Invincible

Kaiju No. 8

Not sure if RWBY counts, but I've had "This will be the day" stuck in my head for like 10 years thanks to season 1's opening music:

Ossan newbie is a good one, I really enjoyed that show too.  We need more anime about older dudes living their best life.

Agree 100%. I've been actively looking for more like it. Kaiju #8 is kind of the sameish. If only this genre could replace isekai as the current fad....
