When Taio Cruz's single "Break Your Heart" hit #1 on the Billboard Hot 100, it helped Ludacris make some chart history.  Luda is featured on the single, so that song represented his 16th trip to the top 10, both as a solo artist and as a guest vocalist.  That means Luda is now tied with Jay-Z as the rapper with the most top 10 appearances on that chart.  In addition to sitting at #1 with "Break Your Heart," Ludacris is also at #10 with his own single, "How Low."
