'San Diego' Appears To Be In-part About Tom Delonge
He shares it was a song that Mark Hoppus did not want to write, however Feldmann adviced him to write about stuff that he did not want to write about.
Here's what he said about the track:
There's clearly a lot of feelings involved with having a best friend who is not in your band anymore, having a best friend with all that stuff that went down. Every band has these issues. To write a song, now, in their minds, to go back to San Diego, playing shows and tipping their hat to the city that allowed them to be a band... to me, Blink put San Diego on the map. If you think of its geographic location, they're the band that made San Diego relevant as a city. I say that with the utmost respect to San Diego because I was born in San Diego, I grew up in San Diego but no body gave a fuck about San Diego. It was just like a place and suddenly Blink happened and it was like Seattle.
The song acts as a bittersweet homage, a goodbye to this city that none of us live in anymore but owe so much to, while acknowledging the interpersonal relationships within the band."
