• The opening track of Christina Perri's Hand or Heart album was also the first song she wrote for the project. "I sat at the piano and wrote this song called 'Trust,' she told Radio.com. "As soon as I did I had a eureka moment, and I immediately knew what I wanted to say."
• The album title was inspired by various failed relationships, where Perri had switched between trusting her head and her heart, and she couldn't figure out which was the right way to go. "I was trying to find the right thing and make the right choices, and because none of the relationships worked out I felt as though I just didn't trust me," she told Radio.com. "So I wrote a song about it. In that moment when I wrote the song, I named the album Head or Heart."
  
  "I knew that 'Trust' would be the first song on the album and set up the album," she added, "and I knew that the theme of the album would be split into two - into head songs and into heart songs."
