• During a June 2012 video interview, Ariana described her debut album as being "'50s, '60s Doo-Wop-inspired." Later in the year, she met up with her label and expressed dissatisfaction with the direction the album was taking. Ariana expressed a desire instead to make the type of '90s urban Pop music she grew up listening to. Most of the previously finished songs for the record were scrapped, except for this song, "Tattooed Heart" and "Honeymoon Avenue," which were all reworked from their original Doo-Wop sound to one with a turn of the century Pop feel.
• The album was originally titled after this song but it was renamed Yours Truly after Ariana decided that the LP felt like a love letter she wanted to sign.
• Ariana Grande joined forces with Tommy Brown for this doo-wop-indebted track. They also collaborated on Yours Truly's opening track, "Honeymoon Avenue."
  
  "I feel like the production kind of took a turn there," Brown remembered to Billboard of "Daydreamin'". "It was like doo-wop-electronic! I worked on that production with Matt Squire… he brought a more electronic vibe and brought a more classic soulful vibe."
• Brown has since become a key collaborator of Grande's, but Yours Truly marked the first Billboard 200-topper for both artists. "Now there's a wall of about 30 of them out there," Brown said. "And I'm happy that [Yours Truly] is the first one that started the journey."
