"808s &amp; Heartbreak" debuted at number one on the "Billboard" 200, selling just over 450,000 copies in its first week. Despite varying responses from listeners, the album received positive reviews from most music critics, who generally commended West's experimentation, and was named one of 2008's best records in several year-end lists. Four singles were released in promotion, including the hit singles "Love Lockdown", which became West's highest "Billboard" Hot 100 debut of his career, and "Heartless". Despite its positive critical reception, the album was largely overlooked as a contender for the 52nd Grammy Awards, although the single "Amazing" received a nomination in the category of Best Rap Performance by a Duo or Group.
