Looks like you’ve lost the track (if you were not fast enough). Lost a Girl mp3 by London based New Young Pony Club was available for free for one day only while ago, but no worries, you can always do some old school. Jump into bus, go to record store and demand vinyl. Why? Because sometimes it’s still fun thing to do! Also needless to mention that the track is catchy, great pop song with delicious punk influence, definitely worth of bus-ride. Some might call them trendy indie hipsters, I call them awesomeness.
