A pair of hit duos switched places at the top of the leaderboard, Macklemore & Ryan Lewis’ follow-up single took the top spot on a 6% week-over-week sales increase, supplanting the one-off team of P!nk and Nate Reuss, which was off by 4% but still sold another quarter-million downloads. Justin Timberlake’s second single is also gaining steam, with a healthy 24% bump. Fall Out Boy made an even bigger move with +42% to reenter the Top 10.

Daft Punk’s Pharrell Williams-sung “Get Lucky,” which debuted last week at #10 on 113k, was off by 29%, selling 81k and dropping to #18 following the initial fan frenzy. We’ll see in the coming weeks whether the infectious, retro-sounding track has what it takes to connect with the mainstream. The top debut was “Brave” from Epic’s Sara Bareilles, which moved 76k digi-units to come in at #20. [HitsDailyDouble]
