Foster the People's "Pumped Up Kicks" tops the 4M mark in US
Foster The People's "Pumped Up Kicks" tops the 4 million mark in digital sales this week. This brings to 50 the number of songs that have sold 4 million digital copies. That's impressive considering there weren't any at this time four years ago. The first song to achieve the feat was "Low" by Flo Rida featuring T-Pain, which topped the 4 million threshold in June 2008.
