Redownloading an already purchased Album

I need to re-download an album I already bought... it shows up completely in my purchase history... but I lost it on my iTunes... so I want to re-download it?... will it charge me again... because when I goto do it... it says I've already purchased some of the song (FYI; I've purchased all the songs) on the list... and in the next window that pops up... it ask me if I sure I wanna purchase it and my card will be charged... in my past experience it has not charged me again... but I don't wanna hit the button yet...

This is in regards to an iTunes Essential...
"Hip-Hop Cool Down Complete Set"
