Mark Hoppus of Blink-182 talked with Maxim:
Originally, we were going to go back in and touch up some of the songs we hadn’t finished. We originally were going to have three to five songs on the deluxe, then we got into the studio and thought we could write some more songs. We ended up writing a bunch more so there 11 total on it. They’re all songs we love, it’s really a double-album.
