Help with iTunes downloads

I purchases an album from iTunes. It started to download but was taking so long and wasting my battery so I wanted to stop it. I went to my purchased playlist and pressed the red stop button with the red circle Arround it that is on the right side of each song. Now all of the songs are gone completely. I went tommy downloads and I can't find them there. I went to the iTunes Store to the album I purchased and it says purchased next to each song but isn't giving my any options to download the items that disappeared and never downloaded. I payed for this whole album and now it is no where to be found.

Help me please!
