Cox also attained a Guinness World Record for the longest consecutive period of chart success (after spending over five years on the Billboard chart continuously), breaking the record was previously held by The Beatles. After growing up in Houston, Texas (where Cox was good friends at high school with Beyoncé, often producing records for the members of Destiny's Child before they signed with Columbia Records), Cox relocated to Atlanta to pursue his professional music career and soon established a close working relationship with his frequent production partner Jermaine Dupri.
