Iphone 6 itunes music will not download.

Me and the wife were sitting going through old 80's Music and remembering the good old days and i bought a couple albums, Ive become used to lightning fast downloads with the Iphone 6 and when i went to look at my downloads it said 50 in cue. I plugged it in and waited a bit and came back to check it and it still said 50 in cue, checked wifi and all my settings and all were straight so i came here and looked about and there was no other mention of it. So i thought i would post this here and see if i can get some help.
