Mumford & Sons' "The Wolf" (Glassnote) leads the pack this week at Modern Rock. The buzzing X Ambassadors song "Renegades" (KidinaKorner) had a strong day leading into its official impact next week. Fueled By Ramen's Panic! At The Disco picks up some early airplay with their new single "Hallelujah." Other winners include RCA's Wolf Alice "Mona Lisa Smile" and Columbia's MS MR "Painted."
