“About You” is about Mike’s feelings on how when he tries to write a song about something other than Chester or his death, it could still be interpreted in that way.

In a 2018 interview with Rolling Stone, Shinoda stated:

I was thinking, ‘God, I have all these ideas for songs that aren’t about Chester or what happened, so I wrote a song about feeling that moment of writing songs. Because not every song is about him and about what happened.
