Mumford and Sons are leading the way in the mid-year non pop charts with their album, 'Sigh No More'. 

While Adele and Lady Gaga take first and second place with 2.25 million and 1.54 million sales respectively, the folk-rockers are just behind after shifting an impressive 982,000 copies of their debut record. 

Billboard.com also added that the album "spent six weeks at No. 1 on the Rock Albums chart and has so far topped out at No. 2 on the Billboard 200".
