“6/8” is one of Blink-182’s most unique songs from their discography. The song has a dark and grim melody with lyrics that touch on themes like depression and fighting to escape a deep hole. It was described by writer Mark Hoppus as very different from their normal style. He told Billboard:

Some of the songs are a little bit more experimental than what we put on the record. There’s a song called “6-8” that’s a very heavy song, it’s in 6/8 time which is why we titled it “6-8.”

The band tweeted on April 27th,

This is the strangest song blink have ever recorded. It’s in 6/8 time. It’s aggressive and one of our favorites from the deluxe because of it.
