So I have many purchases in the music store. All on my iPad Air. However, when I search for some artists, whom I have multiple albums and singles from, I only see some coming up as 'Purchased' so I don't purchase it again. Other singles show the price but when I go into the single, the price next to them song shows PLAY, which means it picks it up as stored on my iPad. When I go to purchases, it shows as a download. Why are someone showing that I already purchased it and others not (but it's on my Purchased list)? Kinda confusing and inconsistent.
