Jeremih and Keri Hilson just earned major upgrades on Billboard’s Hot 100 chart. In chart data released Thursday, the duo each moved at least five slots up the chart, displacing Jamie Foxx (“Blame It”) and Kid Cudi (“Day ‘N’ Nite). Jeremih, fresh off the video release of his #1 R&B/Hip Hop songs charting hit “Birthday Sex,” moved five spots up the chart this week (no.4). But it was Keri Hilson’s “Knock You Down” that took Billboard’s “biggest airplay gainer” title for this week as the single jumped six spots to claim no.7. Hilson’ “Knock You Down,” featuring Ne-Yo and Kanye West, is the follow up to this spring’s hit single “Turnin’ Me On”. In other chart news, Pitbull’s “I Know You Want Me (Calle Ocho)” rose two spots to No.3 while Beyonce’s “Halo” rose two spots to No.6.
