As is becoming common practice these days, there’s also a deluxe edition of Delta Machine available that adds four more tracks after “Goodbye”. Aside from somewhat spoiling the album’s carefully-considered curtain call, the bonus tracks don’t add or detract from the proper LP, instead being more variations on the established themes and sounds (for the curious and/or completist, do note that “Always” stands out more than the others due to its use of electronic tones that could come straight out of an eight-bit video game and Martin Gore’s borrowing a hook from “I Feel Love”).
