How to continue to download a stopped download in iTunes?

Pretty much what the title sais really. Started to download a song on my iPhone and stopped it accidentally. It says I have the song but I can't play it and iv still been charged for it:/ it says check downloads in the store but there isn't the appropriate menu

Any help would be great

Hope you find your answer

There should be a purchased tab somewhere in the itunes store, and click re download
