 "Justified" ended selling four million copies in the United States alone.Although the album established Timberlake's career outside his then-band *NSYNC, Timberlake (who was 22 years old at the time), was "at a crossroads" and felt he was at the stage of being "burnt out", and thought he had lost his voice "in regards to knowing what (and how) he wanted to sing".Timberlake stated that "Justified" had been years in the making, and a record that would re-create its success would be a challenge he was not ready to take.
