While official numbers aren't in yet, sources suggest that some of the biggest sales winners from the Grammy Awards on Feb. 10 include Mumford & Sons, the Lumineers, Frank Ocean, Rihanna and fun.

Music sales for the week ending Feb. 10, as tracked by Nielsen SoundScan, will not be released until Wednesday morning (Feb. 13). However, label sources have indicated that a number of albums and songs are due for big gains when the figures come out.

Among the albums heading for a gain of 50% of more compared to the previous week are album of the year winner "Babel" by Mumford & Sons, fun.'s "Some Nights," the Black Keys' "El Camino," Frank Ocean's "Channel Orange," Miguel’s "Kaleidoscope Dream," Jack White's "Blunderbuss," and Kelly Clarkson's "Stronger."

Of those, the largest percentage gain might belong to Ocean's set, which could post a jump of 120%. A week ago, "Channel Orange" moved 5,000 copies, according to SoundScan. So it might have jumped to 11,000 in the week ending Sunday.

"Babel" looks to be the largest seller for the week overall, as it’s on course to move around 55,000. That would be a jump of 50% compared to the previous frame, when it shifted 36,000.

All of these albums will likely have an even bigger gain next week (ending Feb. 17), when a full week's worth of post-Grammys impact will be felt. This week's charts will only reflect sales generated in the hours during and after the show, through the end of Sunday night.
 
In terms of digital songs, the largest seller of the songs performed on the show could be the Lumineers' "Ho Hey." Forecasters suggest that it sold 140,000 in the week ending Feb. 10. That could translate to a 17% increase for the sales week.

However, "Ho Hey" is a current hit, so thus it was already selling well -- and had perhaps little room to grow. It might be more interesting to look at those songs that will have the largest percentage increases in sales.

Right now, those are looking like Rihanna's new single "Stay" (featuring Mikky Ekko) and Miguel's "Adorn." Both should gain by more than 200% in the week ending Feb. 10, with "Stay" selling perhaps 65,000 and “Adorn” moving 40,000. For the latter tune, which was released last August as a single, it will mark the song's best sales week yet.

Also aiming for big increases are Mumford & Sons' "I Will Wait" (up more than 100% to 48,000), fun.'s "Carry On" (up 131% to 60,000) and "We Are Young" (up 150% to 50,000). "Wait" and "Carry" were both performed on the show, while "We Are Young" won the Grammy Award for best song.
