Songfacts®:

• Maude Latour writes down just about every thought that comes into her head, filling her phone with voice memos and journals with pages of script. She so dedicated to this practice, she even put an argument with a soon-to-be-ex boyfriend on hold so she could record her thoughts right then and there, as they were breaking up. That voice memo became the chorus lyrics to "Block Your Number," a song where she enters that last stage of a relationship - the part where she won't even take his calls.
  
  "We were breaking up, and I said, 'Hold on, stay right there.,'" Latour said on the Songfacts Podcast. "He was like, 'Oh God, I know this is going to be a song.' I said, 'Yes, it will.'"
• Latour was just 20 years old and a junior at Columbia University (studying philosophy and business) when she released this song, which explains the dorm room reference:
  
  If it were perfect, I wouldn't be cryin'
  On the floor of my dorm room, you wait in the lobby
  
  There aren't many Ivy League students who can claim millions of Spotify streams, but Latour has enough passion for both her music and her studies to straddle both worlds. He management pressured her to drop out of school to focus on music, but she refused on the grounds that she can be fully dedicated to both.
• Like Taylor Swift in the '10s, Latour developed a reputation for putting her breakups into songs, like she did on this one. "I do feel kind of bad for my ex now," she told Songfacts. "The lyrics are so immortalized and so personal and are of me speaking directly to him. Of course his new girlfriend hates me, but what else can you do? I own my life story and this is my way of getting closure. It's so meaningful for me and I get to write the chapters of my life."
