STOP A SONG THAT I PURCHASED ON ACCIDENT FROM DOWNLOADING ITUNES?

I was downloading a bunch of songs (on itunes from my iphone 4s) and accidently hit purchase on one i didn't want. I'm using a itunes gift card with credit and I have $1 left now, but the song I want is $1.29 and i purchased one on accident. The accidental one is on pause in my downloads right now, is there a way to delete it from there (i don't want it and it would be nice to get my money back on my gift card) Help

No instant way, you could try and contact iTunes Customer support and have them re-instate the credit.
