Sakanaction’s Ichiro Yamaguchi on AI Lyrics: “Smart But Boring,” “No Scent to Them”

From our other sites

The story

On the September 1 broadcast of All Night Nippon, Sakanaction’s Ichiro Yamaguchi described AI-generated lyrics as “the kind that are smart but not interesting” and said they “have no scent — no color, you could say,” adding that good lyrics are born when they exceed his own imagination. Reactions on 5ch were split: many argued AI and human lyrics should be compared in a blind test, or pointed out that the sense of “AI-ness” is just a preconception on the listener’s part, while others agreed with Yamaguchi’s take, citing the flat contours of AI vocals and the uniformity of AI lyrics.

Sakanaction’s Ichiro Yamaguchi appeared on the September 1 broadcast of “Sakanaction Ichiro Yamaguchi’s All Night Nippon” (Nippon Broadcasting System), answering a listener’s question about what matters most in writing good lyrics.

Yamaguchi explained that what matters most in writing good lyrics is “exceeding your own imagination.” “Even if you write intending to phrase something a certain way, or wanting to write about a certain theme, you don’t end up surprising yourself,” he said.

He considers a lyric complete when it reaches the point of “Huh? That’s not even what I meant to say, but it turned out beautiful” or “Did I really write this?”

But that's just a ripoff of "Shake Hip," right?

If you can tell human from AI in a double-blind test, you win.
6AnonymousSep 3, 2026 15:44
This guy sounds pretty frustrated tbh
Sounds perfectly listenable to me

Re: #6
Exactly

Re: #1 is just coping (a "moral victory" mindset)

Time to time-slip back and crash the Man'yōshū (Japan's oldest poetry anthology)
8AnonymousSep 3, 2026 15:45
I wonder
If you lined up a bunch of lyrics
could you really pick out the AI ones every single time?

It's a radio show — I'd love to see them actually try it
12AnonymousSep 3, 2026 15:47
Like those AI songs made from Harabo Nishi's gags (a comedian known for absurd bits)
The lyrics are completely nonsensical and hilarious
13AnonymousSep 3, 2026 15:47
That's a ripoff of Kome Kome Club
I thought it was the Drifters' "Baban Baban Ban Ban Ban"
15AnonymousSep 3, 2026 15:49
Same kind of thing as saying Utada Hikaru's lyrics lack humanity?
45AnonymousSep 3, 2026 16:19
Re: #15
The one that was the News Zero ending theme had good lyrics though
16AnonymousSep 3, 2026 15:50
Plenty of humans out there stitching together lines they picked up from somewhere too, and it's cringe
67AnonymousSep 3, 2026 16:53
Re: #16
It's all been done already
Twist it and it just turns edgy/try-hard
Same goes for the music, not just the lyrics
17AnonymousSep 3, 2026 15:50
Hearing it's basically just a pile of predictive text makes it sound less impressive somehow
Feels like AI's losing steam lately too, I wonder how that'll go
18AnonymousSep 3, 2026 15:50
Seeing the name in print, it overlaps with Ryoichi Yamaguchi.
I like them both — funny, good talkers
19AnonymousSep 3, 2026 15:51
Saw a Yajuu Senpai song on my YouTube recommendations (an internet meme figure)
Fully AI, MV too, but the quality blew me away
Made me realize how far this stuff has come
22AnonymousSep 3, 2026 15:53
Logical correctness doesn't even matter
as long as it feels vaguely affirming, you're fine
Just grab a word people don't normally use but that clicks the second you hear it — "oh, that one" — with a sideways, unexpected twist, and you win

Honestly, lyric writing looks like exactly the field AI would be best at
23AnonymousSep 3, 2026 15:53
Humanity fought shogi software with everything it had but eventually admitted total defeat
now it's been embraced and put to good use
music's world is still resisting, huh
24AnonymousSep 3, 2026 15:53
It's like how AI illustrations never quite grab you
things with too little irregularity just don't pull people in
66AnonymousSep 3, 2026 16:53
Re: #24
Yeah, it's boring
26AnonymousSep 3, 2026 15:54
Well, that's just the impression the word "AI" gives, isn't it
27AnonymousSep 3, 2026 15:55
> Smashing separate drafts together ("gacchanko")

"Gacchanko" is totally Gemini's catchphrase lol

The big AI models have a sheer volume of knowledge beyond any single person
No human could ever compete on that front
so he's surely using AI heavily
It's just that he's not leaving it entirely up to AI, that's all
28AnonymousSep 3, 2026 15:55
Feels like poetry, where the usable vocabulary is more limited, is actually closer to being in trouble

Poetry might end up being more about the "poet's brand" than the actual content
29AnonymousSep 3, 2026 15:57
AI does tend to line up words that just sound pleasant
30AnonymousSep 3, 2026 15:57
> "It feels smart but not interesting" "To me it just has no scent — no color, I guess"

That's nothing but a preconception based on already knowing it was written by AI
Run a blind test and you won't be able to tell the difference
31AnonymousSep 3, 2026 15:57
Sounds like "you're smart but not interesting" yourself
32AnonymousSep 3, 2026 15:59
Re: #1
They should do a New Year's special guessing which lyrics are Yamaguchi's and which are AI's

If he gets it wrong, no point airing it

Bonus points if Daigo guesses wrong and Gackt yells at him (referencing a variety-show bit)

My kettle broke so I went looking for a new one
almost went with stainless but got enamel instead
34AnonymousSep 3, 2026 16:02
There are a lot of YouTube channels having AI sing lately, and sometimes it's better than the original — pretty impressive
dunno about the lyrics side of things though
35AnonymousSep 3, 2026 16:05
Wonder if he actually knows anything about stainless steel when he says that…
36AnonymousSep 3, 2026 16:06
I want to believe AI still can't pull off suddenly shifting tone to catch the listener off guard
if it can do that, then you probably can't tell them apart anymore
37AnonymousSep 3, 2026 16:06
You guys sounded pretty mechanical/inorganic back when you started too
like "Aruku Around" or "Native Dancer"
though I don't know about the lyrics
39AnonymousSep 3, 2026 16:09
It's because the prompt given for writing lyrics isn't good enough
Just tell ChatGPT ("Chappy") to write a prompt that gives it "scent" and makes it gel-like
52AnonymousSep 3, 2026 16:27
Bet you couldn't tell in a blind test lol
65AnonymousSep 3, 2026 16:50
Re: #52
I think a professional musician could spot it easily
Though you couldn't
I can easily spot it in videos and images too
56AnonymousSep 3, 2026 16:34
AI vocals sound like clean straight lines, kind of jagged and angular
I guess with humans the edges feel rounded off, huh
58AnonymousSep 3, 2026 16:36
Re: #56
It's still just mid-evolution
74AnonymousSep 3, 2026 17:06
If you've actually used it, you'd know getting rid of AI's quirks is nowhere near easy
I use AI 12 hours a day so I'd know
75AnonymousSep 3, 2026 17:12
Re: #74
"I made this with AI! Amazing!" — there's a flood of ridiculous output out there that somehow got the OK looking like that
At this stage, it's a tool that only someone who can actually tell what's wrong with AI output can really use well

Background and Key Points of This Discussion

Yamaguchi’s remark originally came up as an example within a broader discussion of “what makes good lyrics,” not as a blanket condemnation of AI technology itself. On the thread, opinion split between those who read the comment as a claim that “AI loses to humans” and pushed back, and those who agreed with Yamaguchi’s sense of it. Some pointed to the precedent of shogi software, which humans resisted before eventually embracing and putting to use, suggesting music may follow the same path; others held firm that, for now, you can still sense a difference in texture from human work, citing the flat contours of AI vocals and the “lack of irregularity” in AI illustrations. It’s worth noting that whether people could actually tell the difference in a blind test was never verified on the broadcast — it remained at the level of “I’d love to see them try it.”
