Songfacts®:

• Galantis is a Swedish songwriting duo consisting of electronic music production songwriters Christian "Bloodshy" Karlsson (Britney Spears' "Toxic") and Linus Eklöw (Icona Pop's "I Love It.") This synth-laden song featuring vocal effects was released as the fourth single from their Pharmacy album.
  
  Rolling Stone asked the pair when they are making a song with a lot going on, such as "Peanut Butter Jelly," how they know when it's time to stop adding things. Karlsson replied: "That's the key to making great music. I meet so many amazing, talented people making music that I feel like sometimes their downfall is when they don't know when to stop. You're sitting in your studio, you're hearing this song going over and over and over again, and I think it's very easy to get lost."
  
  "One thing that's very good is to play your music for others, in their studio or home. It takes like 10 seconds to realize something is wrong."
• Canadian pharmacist, Marcellus Gilmore Edson, was the first to patent peanut butter, in 1884. He developed the idea of peanut paste as a delicious and nutritious staple for people who could hardly chew on solid food.
  
  A decade later, George A Bayle Junior, a St. Louis doctor and owner of a food products company, came up with his own recipe for peanut butter. The doctor had been looking for a nutritious protein substitute for his patients with bad teeth who couldn't chew meat, and had experimented by grinding peanuts in his hand-cranked meat grinder. After mechanizing the process he started selling peanut butter out of barrels for about six cents per pound.
  
  Peanut butter was originally considered a delicacy and was only served in the finest tearooms; the first reference to peanut butter being paired with jelly was in 1901.
  
  Three years later peanut butter came into the limelight at the St. Louis Universal Exposition by concessionaire C. H. Sumner, where it was promoted as a health food.
