Пожалуй от девяти слов в названии (по восемь - достаточно имеется).
Мне вот всегда нравилась романтичная но не скучная ...
...Secret Service - When The Dancer You Have Loved Walks Out The Door
...Ещё примеры из диско:
Nolans - I'm Never Gonna Let You Break My Heart Again
Boney M - Never Change Lovers In The Middle Of The Night

Pet shop boys-You only tell me you love when you're drunk

Славятся, выходит, Pet Shop Boys замысловатыми названиями - ещё имеется у них:
This Must Be The Place I Waited Years To Leave
I Don't Know What You Want But I Can't Give It Any More - здесь тринадцать слов, пока рекорд...

Ну и конечно же в эту тему сильный хит:
Sensus – Perry Rhodan ... More Than A Million Lightyears From Home ... (полное название именно такое)

The Weather Girls - I'm Gonna Wash That Man Right Outa My Hair

Modern Talking - "Good Girls Go To Heaven, Bad Girls Go (To) Everywhere" - второе "To" не поется, но в названии песни тем не менее присутствует
Fancy - "Na Na Na Na Hey Hey Hey Kiss Him Goodbye"

Roxette - You Can't Put Your Arms Around What's Already Gone - правда, уже поздняя их вещь...

Ken Laszlo - 12345678 - если цифры прописью)))).
MT - The Night Is Yours - The Night Is Mine
MT - There's Too Much Blue In Missing You

Billy Ocean - When The Going Gets Tough, The Tough Get Going

Human League - Rock Me Again And Again And Again And Again And Again And Again (Six Times).Пока произнесешь название этой композиции,она уже закончится:)

De Aal - Een Barg Die Hé Un Krul In De Steert

Вот такая вот вполне дискотечная песенка.
Elton John - I Don't Wanna Go On With You Like That

Вспомнил тему, но не 80-х, а конца 90-х:
The Tamperer feat. Maya - If You Buy This Record Your Life Will Be Better

Le Groupe Carambar - A Boo Goo Doo Flish A Boo Goo Doo Flash

Nada - Dimmi Che Mi Ami Che Mi Ami Che Tu Ami Che Tu Ami Solo Me

Bryan Adams – The Only Thing That Looks Good On Me Is You

Самое длинное название, что я видел.

Rednex - "The Sad But True Story Of Ray Mingus, The Lumberjack Of Bulk Rock City, And His Never Slacking Stribe In Exploiting The So Far Undiscovered Areas Of The Intention To Bodily Intercourse From The Opposite Species Of His Kind, During Intake Of All The Mental Condition That Could Be Derived From Fermentation"

И всё-таки внесу поправку в первое сообщение темы:
От девяти слов в названии. Артикли и однобуквенные союзы/предлоги также засчитываются.
