洋楽ベスト50（英語学習用） 英語のリスニングがだめ。一般の教材を使って長年練習して、そして英語のニュース番組などは多少適応できるようになったとは思うのですが、映画の中の会話や、ニュース番組中でもインタビューなんて全然聞き取れない。歌なんて全くダメ。それでいっその事、英語の歌を教材にしてトライしてみました。聞いて、意味理解して、覚えて、口ずさめるように。夜寝る前に睡眠薬代わりに思い出せるようになったらOK。それで、50曲達成。下は取り組んだものです。どんな歌があったかを、いつでにどこでも調べられるようにWEB上にまとめておくことにしました。 コロナのせいで海外行きもなくなったし、英語学習の意味は薄れたけれども、歌は楽しむことにしました。認知症防止にもなりそうだし。コロナが落ち着いたら一人カラオケでも行ってみようか・・・と。 [1] Killing me softly with his song (Roberta Flack) ref_1 [2] Uptown girl (Billy Joel) ref_1 [3] Separate ways (Journey) ref_1 [4] Imagine (John Lennon) ref_1 [5] Top of the world (Carpenters) ref_1 [6] We Are The World (Michael Jackson, et al.) ref_1 [7] Let it be (The Beatles) ref_1 [8] Arthur's theme (Christopher Cross) ref_1 [9] Last Christmas (Wham!) ref_1 [10] Can't take my eyes off you (Boys Town Gang) ref_1 [11] Hard to Say I'm Sorry (Chicago) ref_1 [12] Have you never been mellow (Olivia Newton-John) ref_1 [13] I'm in the mood for Dancing (The Nolans) ref_1 [14] Let It Go (Idina Menzel) ref_1 [15] We Are all alone (Boz Scaggs) ref_1 [16] Chiquitita (ABBA) ref_1 [17] Mrs. Robinson (Simon & Garfunkel) ref_1 [18] Ai No Corrida (Quincy Jones) ref_1 [19] I Want To Hold Your Hand (The Beatles) ref_1 [20] I was Born to love you (Queen) ref_1 [21] Stranger (Billy Joel) ref_1 [22] Copacabana (Barry Manilow) ref_1 [23] Dancing queen (ABBA) ref_1 [24] Sound of Silence (Simon & Garfunkel) ref_1 [25] Fantasy (EWF) ref_1 [26] Don't Let Me Be Misunderstood (Santa Esmeralda)［悲しき願い］ ref_1 [27] Help (The Beatles) ref_1 [28] HEY JUDE (The Beatles) ref_1 [29] Minority (Geenday) ref_1 [30] Private Eyes (Daryl Hall & John Oates) ref_1 [31] Honesty (Billy Joel) ref_1 [32] Together Forever (Rick Astley) ref_1 [33] Hotel California (Eagles) ref_1 [34] When will I see you again (The Three Degrees) ref_1 [35] Love in the first degree (Bananarama) ref_1 [36] Superstar (Carpenters) ref_1 [37] Sing a song (The Carpenters) ref_1 [38] Anyway you want it (Journey) ref_1 [39] I've Never Been To Me (Charlene) ref_1 [40] You light up my life (Debby Boone) ref_1 [41] A Hard Day's Night (The Beatles) ref_1 [42] All My Loving (The Beatles) ref_1 [43] Eye of the tiger (Survivor) ref_1 [44] Boxer (Simon & Garfunkel) ref_1 [45] Don't Stop Me Now (Queen) ref_1 [46] Tie A Yellow Ribbon Round The Old Oak Tree (Tony Orlando & Dawn) ref_1 [47] YMCA (The Village People) ref_1 [48] Yesterday (The Beatles) ref_1 [49] Take me home Country roads (John Denver) ref_1 [50] Scarborough Fair (Simon & Garfunkel) ref_1

Your Diagnosis
Before revealing the machine’s verdict, predict the BS score for each signal. Higher = more BS (more fluff, less verifiable substance). Drag each slider, then submit to compare your judgment against the engine.
Stuck? Reveal the heuristic lens — how the deterministic page-auditor reads each signal (no AI, pure pattern rules)
These are the structural rules a local, deterministic auditor applies — the same lens you can use to judge each signal. They describe what to look for, not this company’s result.
Classify each sentence as substantive or hollow. Grounding markers — numbers, currencies, dates, technical units, named entities — outweigh marketing adjectives. When fluff sits right next to hard evidence, the fluff is forgiven.
Pull the main entities out of the H1, then check whether they actually recur through the body. A page that announces one thing and then talks about another drifts. Headings with no real sentences underneath read as pseudo-substance.
Count trust words (review, testimonial, rating, verified) against real outbound proof links (Google, Trustpilot, Clutch, G2, Yelp). Lots of trust language with zero verification links is trust theatre. Unlinked logo galleries count against it.
Look at how much sentence length varies. Natural writing varies its rhythm; templated or mass-produced copy is statistically uniform. Very low variation reads as commodity content — unless unique named entities break the pattern.
Inspect the JSON-LD. Is there an Organization or Person schema, and does it carry sameAs links to real external profiles (LinkedIn, socials)? Missing schema or no identity declaration signals an anonymous entity.
Want to apply this lens yourself? The free BS Indicator Chrome extension runs these heuristic checks live on any page. Bear in mind it is a single-page, deterministic tool — it relies only on pattern rules for the page in front of it and does not perform the cross-page semantic correlation this audit uses, so its readout is a starting lens, not the full verdict.

Science, Research & Laboratories BS: Science on Cleaning and Detergents (Masaru Oya) (detergent.jp)
This site is a rare ‘BS-Zero’ specimen, functioning as a high-utility academic archive rather than a commercial entity. It prioritizes technical specificity (pH calculations, sebum chemistry) over every known marketing trope. Its only ‘failures’ are technical/design-based, which actually reinforces its authenticity as a genuine researcher’s repository.
Implement JSON-LD Person schema for Masaru Oya to formally link his academic credentials and sameAs properties (e.g., University profile, ResearchGate). Add an H1 tag to the homepage that clearly states the primary scientific focus to improve structural coherence. Update the ‘English Learning’ sub-section to a sub-domain or clearly distinct subdirectory to maintain scientific topical authority. Replace the manual email obfuscation with a secure contact form to enhance technical professionalism.
The site aligns perfectly with the Science, Research & Laboratories category, focusing specifically on the chemistry of surfactants and cleaning methodologies. The content is authored by a Professor Emeritus from Yokohama National University, providing high-level academic and technical discourse rather than commercial marketing.
“The score of 5 is one of the lowest possible, driven by a near-complete absence of information density penalties and trust theatre. A few points were added only for the archaic technical implementation (lack of H1 and schema) and the slight semantic oddity of mixing detergent science with pop song lists on the same top-level navigation. The site is a benchmark for substance over signal.”
