Josh Ostrander's solo project hits No. 1 on a Billboard chart for the first time.

Mondo Cozmo collects his first No. 1 on a Billboard ranking, rising 2-1 on the Adult Alternative Songs airplay chart (dated Jan. 28) with "Shine." The solo project of Eastern Conference Champions frontman Josh Ostrander hits the top spot with a 14 percent leap in airplay at the format in the week ending Jan. 15, according to Nielsen Music.

Mondo Cozmo has yet to release a full-length or even an EP of material, with only three songs, including "Shine," currently available for sale and streaming.

Concurrently, "Shine" reaches a new peak of No. 31 on Alternative Songs and jumps 33-31 on Rock Airplay with 2 million in rock radio audience (up 10 percent).

Meanwhile, with its Adult Alternative Songs coronation, "Shine" halts the reign of Kings of Leon's "Waste a Moment" (No. 2) after 14 weeks. That's the longest command since Adele's "Rolling in the Deep" (also 14 weeks) six years ago and is tied for the third-longest No. 1 run in the Adult Alternative Songs chart's 21-year history; only U2's "Beautiful Day" (16 weeks) and Coldplay's "Clocks" (15) have logged more time on top:

14, "Bent," Matchbox Twenty, 2000
14, "3AM," Matchbox Twenty, 1997
14, "One Headlight," The Wallflowers, 1996

"Moment" is from Kings of Leon's album Walls, which became their first No. 1 on the Billboard 200 in November and has sold 130,000 to date. The band performed the set's "Reverend" Jan. 18 on NBC's The Tonight Show Starring Jimmy Fallon.
