I can't listen to some of my songs I purchased it says "purchased" but not "play"

I recently just bought the NOW That's What I Call Music, Vol. 57 on the iTunes store and I can't play track 5, 6, 9, and 20. They say "purchased" but when I look in more > purchased > music it doesn't show it. But, if I go to my computer and log into my iTunes there... Account > View My Account > Purchase History/ See All > ....I do see the song versus when I go into Account > Purchased > Songs (ALL) ...I don't see it. I can play all of the songs except those...any help/suggestions?
