You know, it takes one heck of a song to compete with the amazing storylines of popular anime. But composers somehow manage to make their creations stick with you long after the credits roll. If you’ve ever found yourself humming an opening at random during the day, you already know how powerful these tracks can be. That’s also why we’ve rounded up our picks for top spots!
“Gurenge” – Demon Slayer
When “Gurenge” kicks in, you instantly feel the very determination that defines the show. LiSA’s commanding vocals glide over a dramatic rock arrangement, and it all mirrors Tanjiro’s relentless drive. The song also masterfully balances vulnerability and strength, building momentum as it moves toward its explosive chorus.
“Tank!” – Cowboy Bebop
Few openings are as effortlessly cool as “Tank!” by The Seatbelts. They don’t lean on traditional pop-rock energy; this track dives straight into bold jazz, complete with blaring horns and rapid percussion. It throws you headfirst into the iconic space-western vibe.
“Unravel” – Tokyo Ghoul
There’s something hauntingly beautiful about “Unravel” that captures Tokyo Ghoul’s emotional chaos. It might be because TK’s intense vocals convey a sense of inner conflict that perfectly reflects Kaneki’s transformation. Maybe it’s because the song swells and crashes. Either way, you can’t pretend it won’t stick with you.
“A Cruel Angel’s Thesis” – Neon Genesis Evangelion
You might not expect such an upbeat tune to introduce a psychologically complex series, but that contrast is part of its charm. “A Cruel Angel’s Thesis” pairs bright pop with cryptic lyrics, and though the melody is undeniably catchy, there’s a pinch of mystery that hints at deeper themes.
“Again” – Fullmetal Alchemist: Brotherhood

“Again” opens with a burst of urgency. YUI’s energetic performance captures the brothers’ determination, while the driving guitar keeps the pace moving forward. The song feels both nostalgic and futuristic, which mirrors the show’s balance of regret and ambition.
