“21st Century (Digital Boy)” is a song recorded by Bad Religion, originally taken from their 1990 album Against the Grain. It was recorded again on Stranger Than Fiction in 1994, reportedly because Atlantic Records did not “hear a single” on that album. It was this version of “21st Century (Digital Boy)” that finally gave Bad Religion their first worldwide success, and eventually helped Stranger Than Fiction earn a gold record.

The song is an ironic play on the youth from that time, one that was starting to become centered around digital technology.
