When The Guardian named her Artist of the Decade, Llewyn-Smith wrote, "Why Beyonce? [...] Because she made not one but two of the decade's greatest singles, with Crazy in Love and Single Ladies (Put a Ring on It), not to mention her hits with Destiny's Child; and this was the decade when singles particularly R&B singles regained their status as pop's favourite medium. [...] [She] and not any superannuated rock star was arguably the greatest live performer of the past 10 years." In 2013, Beyonce made the Time 100 list, Baz Luhrmann writing "no one has that voice, no one moves the way she moves, no one can hold an audience the way she does... When Beyonce does an album, when Beyonce sings a song, when Beyonce does anything, it's an event, and it's broadly influential. Right now, she is the heir-apparent diva of the USA the reigning national voice." In 2014, Beyonce was listed again on the Time 100 and also featured on the cover of the issue.
