"Guilty Love" is a 2026 Gavinners hit single. It was also one of their last, due to the disbandment of the band after the fall of that year. When Klavier Gavin, the Gavinners' lead member, prosecuted cases in court, he would often have the song play in the background and even has it as his ringtone, as does Wesley Stickler. When a murder occurred during a Gavinners concert, Gavin had Apollo Justice play the song from an audio mixer to show that Daryan Crescend, the second guitar of the band, had made a mistake when playing it. This information later proved useful to Justice in court, when he revealed that Crescend had been the one to murder Interpol agent Romein LeTouse, with the incriminating gunshot audible during the band's performance of "The Guitar's Serenade".
