Confession: I have never downloaded a ringtone.

I know, I know. I should lose major cool points for that admission. After all, ringtones have become such a huge part of pop culture, Billboard Magazine publishes a weekly ringtone chart. A weekly ringtone chart!

Even though my cell phone still rings the old-fashioned way, I find it interesting to know the top songs that are alerting Americans that a call is coming in.

AT&T has released a list of their bestselling ringtones of the year. The top ringtones are listed below.
