Weve all got that theme song we love way too much. Which series did you watch purely to hear the theme song just one more time? Or which show had that ending theme you could never skip?

While Baccano is my favorite anime now that I've watched it all the way through (and multiple rewatches), at first I didn't love the series. I remember having it on in the background while playing Monster Hunter, and really it was the opening theme song that kept me invested until the 4th episode, or so. Then I was fully into the story and Paradise Lunch's 'Guns and Roses' was the perfect OP for the show.

Special shoutouts also to Outlaw Star and Ixion Saga DT, for having both an opening and ending theme I absolutely love. All 3 EDs for Ixion Saga are fantastic in my opinion, but 1st and 3rd are my faves.

Outlaw Star ED-2... not so much. Really just counting the 1st one for this show.

DBS super with this... KA KA KA KA KACHI DAZE!

So no chi no sadame, stand proud, and the naruto opening during the pain fight.

Pretty much every OP and ED to Detective Conan
All so damn catchy

DBZ's episode outro was pretty crazy too. Such hype music to end an episode.

I think there might be too many to name. XD

Agreed, so I tried to give myself a challenge by trying to pick put the shows that had boss intro and outro.

Oh, shit! I forgot about Danshi Koukousei no Nichijou! The OP rocks, and the ED is delightfully goofy, set to a cheap and incoherent high school play.

Openings -
My Hero (Inuyashiki: Last Hero)
Sono Chi No Sadame
Gospel of the Throttle

Seriously, My Hero is so full of win.

Endings -
The Perfect World (B: The Beginning)

honestly there is nothing that even contests that one

Here are some OP songs I love:
All JoJo OP's except "Chase"
Guns N' Roses - Baccano!
We're Not Alone - Rainbow
Ghost In The Shell: Stand Alone Complex both OPs
Answer - March Comes In Like A Lion
Chase The Light - Kaiji
Let Me Hear - Parasyte
Grain - Monster
Tank! - Cowboy Bebop
Ugoku, Ugoku - Girls Last Tour
Most of the openings from Monogatari-series
Fly High - Haikyuu!
Every opening from Free!
Invisible Sensation - Ballroom E Youkoso
Out of Control - Psycho Pass
Found & Lost - Banana Fish
And of course Cruel Angel Thesis from NGE

Some endings I like:
Lithium Flower - Ghost In The Shell: SaC
Long Hope Philia - Boku No Hero Academia (acoustic version)
Just Awake - Hunter X Hunter 2011
Zetsubou Billy - Death Note
Far Cry - Serial Experiments Lain
Magia - Madoka Magica
Uso - Fullmetal Alchemist: Brotherhood
Gomen ne, Iiko ja Irarenai - Kill La Kill

This list became huge and I didn't even mention everything.

I like all of the BHA openings, mainly
Sora Ni Uteba and Odd Future.

*ahem*
SONO CHINO SADAME
JOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOJOOOO
Oh and roundabout of course
and every other JoJo OP

I once masturbated to the beat of the third opening of Overlord, so I guess that one.

Mob Psycho, both OPs are absolute bangers
