So far during Hot Digital Songs' existence, only one song has been able to triple the runner-up's sales in a tracking week: We Are Never Ever Getting Back Together.

Who will sing the second one to do so? My list consists of the 10 artist(s) who had the biggest one-week leads. I decided to group artists if they collaborated on a song that smashed the competition - which probably doesn't really matter for most of them, as featured acts like Wyclef Jean and Wanz are unlikely...

I'm going with Goddess Swift (again), when she releases next year.

Where's Adele?

I decided to make the choices the 10 artist(s) who previously had the biggest leads, rather than subjectively choose the 10 artists who seem to be the most popular right now.
Adele's biggest lead over the competition was 40%, thus her exclusion.
