Each week, Crave tracks the most popular ringtones.
For all we know, the top five ringtones may be cemented in place for all of eternity. The same 10 ringtones make up the top 10 this week, except a few have switched places.
Unk's "2 Step" holds on to the top spot and will presumably do so until everyone in America has downloaded it. Then, we'll all be confused whenever a phone rings, because everyone will have the same ringtone.
