So we have a new album measurement (see next item), but this is a singles business (we know that because we read it in Billboard), and here’s what that looks like at the moment. P!nk returns to the top spot, replacing Bruno Mars, who was #1 the previous week thanks to a 69-cent sale price at the iTunes Store. The lone newcomer was Luke Bryan, who enjoyed a rather dramatic 526% week-over-week sales increase.

1. P!nk f/Nate Ruess, “Just Give Me a Reason” – 283k
2. Macklemore & Ryan Lewis, “Can’t Hold Us” – 186k
3. Florida Georgia Line f/Nelly, “Cruise” (remix) – 179k
4. Rihanna f/Mikky Ekko, “Stay” – 176k
5. Macklemore & Ryan Lewis, “Thrift Shop” – 167k
7. Luke Bryan, “Crash My Party” – 164k
6. Bruno Mars, “When I Was Your Man” – 166k
8. Justin Timberlake f/Jay-Z, “Mirrors” – 127k
9. Imagine Dragons, “Radioactive” – 124k
10. Icona Pop f/Charli XCX, “I Love It” – 116k

Two more country singles—Tim McGraw’s “Highway Don’t Care” featuring Taylor Swift, and Hunter Hayes’ “I Want Crazy”—occupy the #11 and #12 slots, respectively, both selling north of 100k. The best-selling debut was Avril Lavigne’s “Here’s to Never Growing Up,” her initial foray on new label Epic. [HitsDailyDouble]
