I want to buy an album on iTunes, but I don't want it ever to play unless I purposely select it. That is to say, I want it available, but, if I click "play all songs" on my iPod or in my iTunes, I don't want my fifty Army running cadences to play ever

. I just want them in my library so I can create my own special playlist so I can learn them when I have time with my iPod. Is there a way to do this? Is that what the checkmarks are next to the songs?
Any help would be greatly appreciated!
