CBS' broadcast of the 53rd Grammy Awards shines bright on the Billboard sales charts this week, as a bevy of acts earn gains thanks to the show. Impressive, considering Nielsen SoundScan's tracking week ended at the close of business on Sunday night -- so our charts only reflect a few hours' worth of impact from the show, and much of that impact is felt digitally.

The show -- which, with 26.5 million viewers, was the most-watched Grammys in 10 years, according to Nielsen -- helped at least nine albums earn gains in the top 20.

Near the top of the heap is Best New Artist nominee Mumford & Sons with its "Sigh No More," vaulting 11-2 with 49,000 (up 99%). It's a new chart high -- and the set's second-best sales week. Not bad for an album that came out exactly a year ago today (Feb. 16, 2010). The track that the band performed, "Little Lion Man," re-enters the Digital Songs chart at No. 58 (45,000; up 86%).

Mumford earned a performance slot on the show on their own, plus in a combo package with the Avett Brothers and Bob Dylan, saluting acoustic music. The Avett Brothers' "I and Love and You" bounds back onto the list at No. 62 with 9,000 (up 256%).

As for Dylan, only one of his albums sold more than 2,000 copies this past week. Perhaps because Dylan's fan base skews older -- and may have not rushed to their computer to download an album on Sunday night -- we could see a bump in sales for him next week.

The act that Mumford lost to for new artist, jazz singer/bassist Esperanza Spalding, sees her "Chamber Music Society" album return to No. 1 on our Contemporary Jazz Albums chart with a gain of 243%. The set sold 3,000 this past week, but that wasn't enough for it to re-enter the Billboard 200.

Though Spalding's surprise win was certainly buzzworthy, that was nothing compared to the "OMG" moment at the tail end of the show when Arcade Fire won album of the year for its "The Suburbs" set. It beat out Eminem's "Recovery," Lady Antebellum's "Need You Now," Lady Gaga's "The Fame Monster" and Katy Perry's "Teenage Dream." In turn, "The Suburbs" rallies 80-52 on the chart with 12,000 and a 56% gain.

Clearly basking in the glow of his hit film "Never Say Never" -- in addition to multiple Grammy nominations and a performance slot on the show -- Justin Bieber has three rising albums in the chart's top 40. His "My World 2.0" jumps 17-3 (48,000; up 145%), "My Worlds Acoustic" vaults 47-10 (35,000; up 240%), and "My World" rises 100-39 (14,000; up 162%). Next week we'll see the Bieb's "Never Say Never: The Remixes" set, which was released on Monday, Feb. 14, bow on the chart.

Bieber's "Never Say Never" track motors 31-12 on Digital Songs, shifting 119,000 downloads (up 120%).

Bruno Mars -- who performed on the Grammys and won an award during the pre-show -- sees his "Doo Wops & Hooligans" get pushed down two spots to No. 6 despite a 24% sales gain. Blame all of the hot and heavy action ahead of it on the chart.

Grammy performer and rap album winner Eminem zips 10-7 with "Recovery" (38,000; up 51%). Rihanna -- who got two performances on the broadcast -- falls three to No. 8 with "Loud" (37,000; up 24%). Like Mars, she's pushed back despite her handsome gain.

Elsewhere in the top 20, the "Grammy Nominees 2011" compilation rises 15-11 (33,000; up 52%), performer and nominee Katy Perry holds at No. 13 with "Teenage Dream" (32,000; up 38%) and big winner Lady Antebellum climbs 23-17 with its "Need You Now" set (28,000; up 60%). The latter act took home the awards for best country album, record of the year and best country performance by a duo or group with vocals. In addition, the three members also shared in the trophies for song of the year and country song. Their song "Need You Now" re-enters the Digital Songs chart at No. 42 (59,000; up 150%).

We'll see further gains next week on the charts, once a full week's worth of impact is felt from the Grammy Awards.

Overall album sales in this past chart week (ending Feb. 13) totaled 6.4 million units, up 17% compared with the sum last week (5.5 million). Digital track sales this past week totaled 26.8 million downloads, up 9% compared with last week (24.6 million).
