Fun., Lumineers, Justin Timberlake Get Grammys iTunes Bump

What a difference a week, and a couple of Grammy Awards, makes. Following their wins at Sunday night's 55th annual Grammys, a number of the night's honored artists and performers enjoyed an immediate sales bump on the iTunes charts.

Among the biggest gainers were the two-time nominees the Lumineers, whose breakthrough song, "Ho Hey," jumped up from #5 to #1 on the iTunes singles chart as of Monday morning (February 11). (iTunes was unable to provide data for the morning before the Grammys in order to compare the acts' overnight movement.) Album of the Year winners Mumford & Sons
 charged back into the top 10 with "I Will Wait," which was lodged at #3. Another gainer was Justin Timberlake, whose comeback single, "Suit & Tie," moved six to #4 after his electrifying performance
 on the broadcast.

Rihanna, who also played on the show,
 skipped up to #5 with her ballad "Stay," followed by Fun., who won Best New Artist
 and Song of the Year for "We Are Young." Their latest single, "Carry On," which they played in the midst of a driving rainstorm
 on the show, also slid into the top 10, lodging at #6.

The iTunes album chart was a virtual Grammys takeover, as Fun rocketed to #1 after not even showing up in the top 10 the week before. They were followed by the deluxe edition of Mumford's Babel (#10 last week), as well as the regular version at #3, pre-orders for Timberlake's The 20/20 Experience (due out March 19), The Lumineers' self-titled album (#4 last week), the Black Key's El Camino and Alabama Shakes' Boys & Girls at #8.

Among other performers who enjoyed a singles sales uptick: Maroon 5 ("Daylight" was up two spots to #7) and Ed Sheeran, whose "The A Team" landed at #12. Even if they didn't make it into the top 10, plenty of other Grammy acts crowded the top 40 iTunes singles chart.

Among them: Taylor Swift, "I Knew You Were Trouble" (#13), Alicia Keys, "Girl On Fire" (#14), Black Keys, "Lonely Boy" (#15), Hunter Hayes, "Wanted" (#16), Fun. "Some Nights" (#17), Drake's new single, "Started From the Bottom" (#20), Gotye "Somebody That I Used to Know" (#22), Justin Timberlake's post-Grammys single, 
"Mirrors" (#23), Miguel's, "Adorn" (#24), Carrie Underwood, "Blown Away" (#26) and "Two Black Cadillacs" (#38) and Kelly Clarkson's "Stronger (What Doesn't Kill You)" (#28) and "Catch My Breath" (#33).
