NEW YORK (December 17, 2012)--For the second year in a row, Adele has dominated the music charts, according to Billboard, which has named her its top artist of 2012.

Her album "21" is also the year's top album.

The album was released in February 2011, and its continued popularity may not all be about Adele.

Few artists released albums this year that reached the popularity that Adele's did last year.

Most of 2012's biggest hits were singles that did little to boost album sales of the acts that released them.

Billboard says the year's three top songs are Gotye's "Somebody That I Used to Know," Carly Rae Jepsen's "Call Me Maybe" and fun.'s "We Are Young."

In other year-end categories, Billboard lists Adele as top female artist while Drake takes top male honors.

One Direction is the top new artist and Maroon 5 is the year's top group.
