Ideal song length
What is your preference for song length? I wonder if there is an ideal song length that aligns with a person’s attention span and enables the most impact?
It seems 2 to 3 minutes is the standard in most of the 60s music, and it got longer from there, almost to the point today people criticize the old music (60s) was too short. In one article, they explain why most songs in the 50s and 60s were on average 3 minutes or less.
In 1949, RCA introduced a 45 rpm disk that quickly overtook the 78 and made it obsolete. These 45s were better than 78s in numerous ways. They were made of vinyl instead of shellac, which made them more durable and more easily portable. They were also cheap to make and to buy, which made them easy to market to teenagers in the mid-1950s. Like the 78, the 45 also holds about three minutes of music (depending on the range of sound a song required and the depth of the groove in the disc).
For a band to get its songs played on the radio, it needed to have a 45. Artists complied. This invented what was known as the “single,” for a record containing a single song. The 45 record was cheaper for Americans to buy than a full album and easier for radios to share, making the single in many ways the bedrock of American music.
Did technology make a difference?
It makes sense to assume that since the basis of the three-minute song was the 78 and then 45 rpm single, then songs would become longer as technology evolved.
And there have, of course, been bands that wrote songs longer than four minutes even before the music industry switched to CDs. Rush and Jimi Hendrix have both recorded 20-minute-long songs. Pink Floyd, Led Zepplin, and Bob Dylan all have 10-minute songs. In no way are long songs unheard of in music, but the average song length is still — even as the industry has evolved almost entirely to digital media — under five minutes.
Another interesting article I came across suggests 2:42 (2 mins, 42 secs) is the ideal length for a song, going back to the 60s standard.
In music, brevity can be the soul of listenability. One of the most obvious traits of the “most unwanted” song ever recorded is its 22-minute length. If that monstrosity lasted two minutes and 42 seconds, maybe more people would want to hear it.
Joshua Allen of The Morning News would agree that short songs are best. He wrote last week that the perfect track length is precisely 18 seconds short of three minutes – making 2:42 a kind of golden mean of audio.
Most of us here I am sure would agree the best pop/rock music was created in the 60s and early 70s. Interestingly as the data suggests, the songs on average were the shortest in length in the 60s, at around 2:30 minutes (150 seconds) in the early 60s to around 3:20 minutes (200 seconds) by the early 70s, as illustrated in the graph below.
In a 2019 “Digital Music News Article”, it mentioned:
According to a new report, the average pop song is now significantly shorter.
The average song length on the Billboard Hot 100 has decreased by 20 seconds in the past five years. Songs now average 3 minutes and 30 seconds.
Anyway just some interesting info I uncovered about song lengths. Personally in my job over the years when doing technical or sales presentations, keeping it relatively short and sweet was always important for maximum impact, and I wonder if the same apply to music. The data seems to suggest songs got increasingly longer after the 60s and 70s as the music became increasingly less inspired and inferior. Thoughts?
Despite all the data suggesting shorter songs are better, Stairway to Heaven, and Hey Jude are 8:03 and 7:06 mins long respectively. Yesterday and Sounds of Silence are 2:06 and 3:06 respectively, so there is no firm formulaic rule either it seems.
