Songfacts®:

• This is the closing track of 8:18, the fifth studio album by the metalcore band The Devil Wears Prada. Their frontman Mike Hranica told Artist Direct: "The entire process of tracklisting and building the album, I always said, "'In Heart' has to close the album. This is the way the album needs to end. The vocals at the end of the song are the ideal conclusion to 8:18! That's my perception of 'In Heart.' It's the reflection of that song for me. It's way I imagined it. It's that big ending."
• The song ends with Hranica exclaiming, "Oh my gosh, I want to jump out of a window now or drive off a bridge." The vocalist recalled to Artist Direct: "We were writing in Portland when I demoed out that song. I was at the condo we were staying at writing the lyrics and working on the vocal patterns for the song while the guys were at a practice space jamming out songs. I texted or called Chris (Rubey, guitar) immediately. I just lost my mind. I said, 'I just came up with this line for the song and it feels massive to me. It feels like the perfect end to the song, and it has to end the record.'"
