Apparently, the perfect song length is two minutes and 42 seconds. According to "scientists" in an article posted on The Morning News, the perfect song length is closer to three minutes than two, "but definitely shorter than three minutes" (that's when "song bloat" sets in).
The example that set the time was The La's "There She Goes," clocking in at 2:42. According to the article, other examples include "This Charming Man" by The Smiths, "Get Up" by R.E.M. and "California Dreamin'" by The Mamas & the Papas.
Writer Joshua Allen sums it up with this:
"Let's look at Sgt. Pepper. 'Lovely Rita' is two minutes, 42 seconds. It delivers that psychedelic vibe and a coda but then gets the hell out of your life."
We took a look through our record library to see if this theory holds true. Click through the gallery for some well-known classics and Radio 3 favourites that clock in at the perfect song length. Maybe there is something to this magical number...
DO YOU BELIEVE IN THIS THEORY?
What is the best song that clocks in at 2:42?
