Billboard Magazine has a list each week of hot ringtones. The songs range from hip hop to latin to rock.
Mancini's "Pink Panther" has been on the top 40 ringtone list for more than two years, for example. And artist Koji Kondo has been on the charts for 162 weeks with the Super Mario Brothers theme.
So what makes a ringtone popular? A song with a great hook or an instrumental?
Tim Page, the music critic for the Washington Post, talks about some of this week's Billboard picks with Robert Siegel and Melissa Block.
