the perfect song length has been found! 2 minutes and 42 seconds...if that's how long your song is, then it's going to be a hit!

What else is at 2:42? “Don’t Do Me Like That” by Tom Petty. “Divine Hammer” by the Breeders. “Helplessly Hoping” by Crosby, Stills & Nash. “Get Up” by R.E.M. “California Dreamin’” by the Mamas & the Papas. “This Charming Man” by the Smiths.

You need more proof? Jerk. 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.

Compare that to “With a Little Help From My Friends.” It’s a mere two seconds longer but feels like it drags on for hours. Maybe it’s Ringo, maybe it’s the tedious melody—or maybe it’s the two goddamn seconds.
