Radio Edit

In music, a radio edit is a modification, typically truncated, to make a song more suitable for airplay, whether it be adjusted for length, profanity, subject matter, instrumentation, or form. Radio edits may also be used for commercial single versions, which may be denoted as the 7" version. However, not all "radio edit" tracks are played on radio.

Radio edits often shorten a long song in order to make it more commercially viable for radio stations. The normal length for songs played on the radio is 3 to 4 minutes.

Вопрос.
1. Почему выбрана именно такая длительность? В чём суть нормальности ?

Подсказка. (Видеоряд можно не смотреть, хотя и там доп. намёк есть).

Fleetwood Mac - Big Love

Пипетка не едет

О тут чём пишет женатый муж ?

Инфантилизм, общество и рефлексия

Counting Crows - Mr. Jones

Lyrics.

Sha, la, la, la, la, la, la
Mmm
Uh huh

I was down at the New Amsterdam
Staring at this yellow-haired girl
Mr Jones strikes up a conversation
With a black-haired flamenco dancer
You know, she dances while his father plays guitar
She's suddenly beautiful
We all want something beautiful
Man, I wish I was beautiful

So come dance the silence down through the morning
Sha la, la, la, la, la, la, la
Yeah
Uh huh
Yeah

Electra/Oedipus Complex

U2 - Staring At The Sun

Lyrics

Summer stretching on the grass
Summer dresses pass
In the shade of a willow tree
Creeps a crawling over me
Over me and over you
Stuck together with God's glue
It's going to get stickier too
It's been a long hot summer
Let's get undercover
Don't try too hard to think
Don't think at all
I'm not the only one
Starin' at the sun
Afraid of what you'd find
If you took a look inside
Not just deaf and dumb
Staring at the sun
Not the only one
Who's happy to go blind
