Of all the songs, on all the iPods, in all the land, these are the most popular right now


Radio hits rule this month on the streets and the treadmills. Nicki Minaj, Katy Perry, and Madonna each have new singles destined for playlist glory. But it's not just pop divas who are prevailing. Carrie Underwood's latest track retains a few country touches, Skrillex and Sirah are climbing the charts with a boisterous dubstep anthem, and although most hip-hop is too slow to crack the top 10, J. Cole's aptly-titled "Work Out" is proving to be an exception.

Here's the full list of this month's best running songs, according to votes placed at RunHundred.com, the web's most popular workout music website.
