“BACK2YOU” is a dark collaboration between rock-rapper nothing,nowhere., blink182 drummer Travis Barker, and R&B singer blackbear, focusing on toxic attachment to a lover who only returns pain. Although blackbear didn’t name them previously, he dabbled in punk rock during his early days.

On May 20, 2019, nothing,nowhere. released an initial snippet of the song on his Instagram profile.
It was then later previewed on blackbear’s Instagram story, both n,n. and Travis released screenshots of the audio file shortly after, revealing the title.
