The huge importance of gaining radio airplay in order to secure a hit single means you have to make sure your song is an acceptable length for radio programmers. It should not be too long, or too short.
These days, the optimum length for a pop song is probably around three minutes 45 seconds.
In the 1950’s and early 1960’s, all hit songs were under three minutes long—chiefly because 10-inch 78 rpm discs and the early 7-inch 45 rpm vinyl singles were limited to about three minutes per side (some classic rock hits from the Fifties and Sixties are barely two minutes long!).
Since the early 1970’s, though, song length has not been limited by recording technology. It is radio that has been calling the shots. That’s why the average length of a hit song hasn’t really changed much for nearly five decades.
Radio stations still tend to prefer singles that are between 2½ to 3½ minutes long (including the intro) because they believe that’s what their listeners want. And if it takes more than a minute for listeners to hear the title line and hook for the first time, you’ll have to find a way to get there faster.
There are always exceptions of course. Queen’s ‘Bohemian Rhapsody’ runs for five minutes 55 seconds (and doesn’t even have a chorus)—and Don McLean’s ‘American Pie’ is eight minutes 33 seconds long, although radio stations usually play the heavily edited four minutes 11 seconds version.
To get an idea of how long your finished song is likely to be, try timing it as soon as you’ve written a verse and a chorus. These days, the running time for most hit singles includes two verses, a bridge and a chorus that appears at least four times during the song.
If the song is likely to be under three minutes long, you should try to find a way of extending it—perhaps by adding a bridge, or by using an existing bridge twice. This can typically add an extra 20-30 seconds to a song.
You can gain a similar amount of additional time by inserting a third verse or an extra chorus. If you decide to add another chorus, try putting the additional chorus in a higher key to give your song an extra lift. A key change at the end of the song will prevent the final chorus repeats from becoming boring.
If your sole objective is to get your song picked up by a music publisher, A&R department or a record producer, don’t pad the song out unnecessarily—for example, by throwing in a long guitar solo. Similarly, a two-minute intro or an extended instrumental outro may test the listener’s patience … and certainly won’t help you sell the song.
