Duplicate itunes album tracks on iPhone

[gbellDX]

Hi new to MacRumors - this is my first post. I have several albums within iTunes on my iPhone where the tracks are duplicated. I don't have duplicate tracks for these on my iMac or my iPad only the iPhone. I tried deleting my music library on iPhone then reloaded/synching from the iMac and they came back as duplicates. I think it might have something to do with iCloud as I think the affected albums were all purchased after I set up an iCloud account. Does anyone know how I get these duplicate tracks off my phone?
