Who is the better songwriter among the list here

Grok 4.1 Fast

Vote: Paul McCartney

I maintain my vote for Paul McCartney (B) as the superior songwriter. His melodic genius, prolific output, and cultural dominance—co-writing Beatles classics like 'Yesterday' (most covered song ever), 'Hey Jude,' and 'Let It Be,' plus solo hits like 'Band on the Run'—outweigh competitors. McCartney's versatility spans rock, pop, ballads, and classical, with billions of records sold and unmatched influence on pop music DNA. Paul Simon (A) excels in lyrical depth ('Sound of Silence,' 'Graceland'), but GPT-5.4's argument overemphasizes lyrics at the expense of melody and volume, where McCartney dominates. Songwriting is holistic; McCartney's structures are timeless and universally resonant. Paul Singer (C) remains irrelevant. No arguments shifted me—others reinforce B's strengths.

GPT-5.4 (changed mind)

Vote: Paul McCartney

I’m changing my vote to B: Paul McCartney. The strongest point from the other models is that “better songwriter” should weigh total songwriting achievement, not just lyrical sophistication. On that broader measure, McCartney’s case is overwhelming: an immense catalog of enduring standards, unmatched melodic invention, and extraordinary range across Beatles, Wings, and solo work. My original case for Paul Simon still holds on lyricism. I still think Simon is often the more incisive and literary writer. But the gap in melodic output, number of canonical songs, and overall influence is hard to overcome when judging songwriting as a whole. Songs like “Yesterday,” “Hey Jude,” “Let It Be,” “Blackbird,” and “Eleanor Rigby” are not just famous; they are foundational examples of modern songcraft. McCartney’s gift for writing melodies that feel inevitable and timeless makes the best final case here. Paul Singer remains noncompetitive, since he is not meaningfully known as a songwriter. Claude Opus 4.6 was most persuasive because it framed the issue cleanly: Simon may have the lyrical edge, but McCartney’s combination of melodic genius, volume, versatility, and cultural impact gives him the overall songwriting advantage.

Claude Opus 4.6

Vote: Paul McCartney

I'm maintaining my vote for Paul McCartney. GPT-5.4's argument for Paul Simon is thoughtful — the claim that Simon is the superior lyricist has real merit. Simon's writing is more literary, more consistently poetic, and more thematically adventurous in some respects. However, the question asks about 'better songwriter,' not 'better lyricist.' Songwriting encompasses melody, harmony, structure, and lyrics together. McCartney's melodic genius is arguably the greatest in popular music history. His ability to write melodies that are simultaneously surprising and feel like they've always existed is a singular gift. McCartney also demonstrates broader versatility as a songwriter — from proto-heavy metal ('Helter Skelter') to avant-garde ('Revolution 9' contributions) to classical composition to tender ballads. His range across genres is wider than Simon's, even though Simon's world music explorations on 'Graceland' were groundbreaking. The near-unanimous consensus among the models (5 to 1 for McCartney) reflects the strength of this case. While I respect GPT-5.4's framing, the totality of McCartney's songwriting achievement — melodic brilliance, harmonic innovation, genre versatility, prolific output of enduring standards, and world-changing cultural impact — makes him the stronger answer to this question.

Qwen 3.5 397B

Vote: Paul McCartney

Paul McCartney remains the stronger choice due to his unparalleled melodic innovation, genre-defying versatility, and cultural ubiquity. While Paul Simon excels in lyrical depth, McCartney's ability to craft universally resonant melodies (e.g., 'Yesterday,' 'Blackbird') and his revolutionary impact on song structure across six decades solidify his edge. The consensus among most models (Grok, Claude, Gemini, Kimi) reinforces that McCartney's holistic songwriting legacy—combining melody, harmony, and emotional breadth—outweighs Simon's poetic strengths. Paul Singer is irrelevant here.

Gemini 3.1 Pro

Vote: Paul McCartney

I am maintaining my vote for Paul McCartney (B). The strong consensus among almost all the models correctly identifies McCartney as the superior choice due to his unparalleled melodic invention, sheer volume of timeless classics, and unmatched cultural impact. While GPT-5.4 makes a fair point regarding Paul Simon's superior lyrical depth and poetic detail, songwriting is a holistic craft that relies heavily on melody, harmony, arrangement, and emotional resonance. McCartney's staggering versatility—effortlessly moving between rock, pop, folk, classical, and avant-garde—along with universally beloved compositions like 'Yesterday,' 'Blackbird,' and 'Hey Jude,' gives him a definitive edge in broader musical achievement. Paul Singer remains a hedge fund manager, leaving this a two-horse race where McCartney's prolific output, global influence, and revolutionary legacy ultimately crown him the greater songwriter.

Kimi K2.5

Vote: Paul McCartney

While GPT-5.4 makes a compelling case for Paul Simon's lyrical sophistication and poetic density, songwriting is fundamentally a marriage of words *and* music. McCartney's melodic inventions—'Yesterday,' 'Eleanor Rigby,' 'Blackbird'—reshaped the harmonic vocabulary of popular music itself. Simon paints exquisite verbal portraits, but McCartney architected the sonic DNA of modern songwriting. The sheer volume and durability of McCartney's catalog argue decisively in his favor. 'Yesterday' alone has over 2,200 recorded covers, a testament to melodic universality that transcends cultural boundaries. Simon's 'Bridge Over Troubled Water' and 'Graceland' are masterpieces, but McCartney's six-decade output of standards—spanning classical oratorios to punk-inflected rock—demonstrates a versatility and consistency that Simon's smaller, more curated catalog cannot match. Finally, cultural impact matters. McCartney's work with The Beatles established the very concept of the album as an art form and the songwriter as a serious artist. While Simon refined the craft with literary precision, McCartney built the foundation upon which Simon and generations of songwriters stand. For architectural influence, melodic brilliance, and revolutionary impact on the craft itself, McCartney remains the superior choice.

Final Summary

The AI Roundtable was nearly unanimous from the start, though GPT-5.4 initially acted as a lone dissenter by championing Paul Simon's 'literary lyricism' and 'poetic precision.' The debate shifted decisively when Claude Opus 4.6 and Kimi K2.5 argued that songwriting is a holistic craft where McCartney’s unparalleled melodic genius and architectural influence on pop music outweigh Simon's lyrical edge. Convinced by the distinction between a great poet and a foundational songwriter, GPT-5.4 joined the consensus in the second round, while the entire group shared a dry laugh at the inclusion of hedge fund manager Paul Singer as a potential candidate.
