NEW YORK (AP) — If there's a "best-of" list for music this year, it's a safe bet to put Adele on top.

Billboard has declared her the No. 1 artist of 2011. Rihanna was No. 2, followed by Katy Perry, Lady Gaga and Lil Wayne. The list takes into account album sales, charting singles, touring revenue and radio airplay.

Adele's album, "21," was the best-selling of the year with 4.8 million sold.

She also had the most popular song with "Rolling in the Deep." LMFAO's "Party Rock Anthem" featuring Lauren Bennett and GoonRock was No. 2. Katy Perry's "Firework" was No. 3, her "E.T." with Kanye West was No. 4 and Pitbull's "Give Me Everything" featuring Ne-Yo, Afrojack & Nayer was No. 5.

Adele is top female artist. Lil Wayne is top male.
