I got an iTunes gift card in a gift swap, and so I purchased some new songs to add to my running (and Shamrock Marathon) playlist. I run without music and actually prefer it now, unless I am on the treadmill or running longer than 15 miles.
Chris Brown - Beautiful People
Chris Brown - Yeah 3x
Fitz & the Tantrums - Money Grabber
Phoenix - 1901
Gym Class Heroes - Stereo Hearts
The Naked and Famous - Young Blood
Kevin Rudolf - I Made It
Kevin Rudolf - Let It Rock
Passion Pit - Little Secrets
Junior Senior - Move Your Feet
Jason Derulo - Don't Wanna Go Home
New Kids on the Block & Backstreet Boys - Don't Turn Out the Lights
I also have CDs by the Dropkick Murphys, Rihanna, and Foster the People on my Amazon Wishlist with the intention of putting some songs from those albums on my running playlist.
