Having blanketed Sunday night's Grammys telecast with ads and promotions (including heavily discounted prices on Grammy-nominated artists and exclusive promotions on recent and upcoming LPs by Taylor Swift and Justin Timberlake), American retailer Target has partnered with a recent Grammy winner and an upstart rock group to expand and reissue two albums.

Babel, the sophomore album by folk-rockers Mumford & Sons, and Night Visions, the studio debut by pop-rockers Imagine Dragons, have both been repackaged with retailer-exclusive content.

The British-born Mumford & Sons have eked out quite the niche performing dusty, banjo and acoustic guitar-laden folk rock that's taken them from small clubs to arenas in only a few short years. They've established themselves as a Grammy favorite, earning a nomination for Best New Artist in 2011 and both Record of the Year and Song of the Year in 2012 for "The Cave." In 2011, they also earned high marks for their performance on the award show broadcast, sharing the stage with fellow folk-rockers The Avett Brothers and a young upstart named Bob Dylan.

Second album Babel continues the long list of achievements for the group: it was the fastest-selling album in England in 2012, was the second-highest selling album in America the same year, and was nominated for four Grammys this week, taking home a trophy for Album of the Year. This new reissue includes three bonus tracks from a previous, non-exclusive deluxe reissue - including a cover of Simon & Garfunkel's "The Boxer" with bluegrass musician Jerry Douglas and Paul Simon as featured guests - and adds three new live renditions of songs from both of their studio albums.

After the jump, "It's Time" to check out a hefty deluxe edition by Imagine Dragons!

Recorded over three years, Night Visions, the debut disc by Las Vegas quartet Imagine Dragons, is divided between throwbacks and new trends. Lead single "It's Time," with its throaty chorus and mandolin-and-huge-drums hook, wouldn't seem out of place on a Hooters compilation; follow-up "Radioactive" is a mix of arena rock and dubstep. The whole disc is equally at home on your car stereo or through a solid PA system at a party or dance hall, and now there's plenty more Imagine Dragons to go around. This new edition also features tracks (five, in total) from a previous deluxe edition only available at electronics retailer Best Buy, and adds another two exclusive tracks. (All seven tracks have been released on various EPs from the band between 2009 and the present.)
