I was comparing the App Store, which lets you freely set prices.

iTunes Store does offer you some control, within certain limits. You can set the “price tier” for different songs, which is why you see some songs for 69¢, some for 99¢, and most for $1.29. If you’re a prog-rock band who put out an album with 20-minute songs, one song per side, then you mark the songs as “album-only” and set the price for the album (or at least the price tier). Or you can divide the song into segments and let people buy those as individual tracks. I’ve seen both approaches.
