Looking for a background song from the show.

My girlfriend recently showed me the song True Believer by Hayley Williams. I immediately clocked that the instrumental heavily reminded me of a background song from the walking dead but I cant find it. You can hear the instrumental I'm talking about in the beginning of the song. If anyone knows the song I'm talking about or a scene it plays in I would really appreciate it. I already checked Lori's death and the pike scene bc I thought it would be in one of those but neither was correct.
