It eventually sold 749,000 album equivalent units in its first week of sales, and debuted at number one on the Billboard 200. In 2018, articles by The Guardian and Rolling Stone called him "the definitive pop star of his generation" and "perhaps [the] biggest post-Justin Timberlake male pop star of the new millennium", respectively. Shortly thereafter, Drake collaborated with British hip hop promotion Link Up TV on July 7, releasing a freestyle as a part of the promotion's 'Behind Barz' segment, before releasing another freestyle a week later after featuring on Charlie Sloth's long-running Fire in the Booth program on BBC Radio 1Xtra. Drake then earned his sixth number-one hit with "In My Feelings" on July 21, which also spawned the viral "#InMyFeelingsChallenge" or "#KiKiChallenge".
