Apple just added a “groundbreaking” feature to its iTunes store called “Complete My Album” that lets music fans complete partially downloaded albums for a reduced price. Say you’ve already downloaded one song from an album but now want the rest of it without having to repurchase the one song you already have. (Certain longer length songs can only be had when purchasing an entire album, so this situation pops up more than you might think.) With “Complete My Album,” Apple credits your account for the already purchased song(s), leaving you to just pay the balance for the remaining songs. Very thoughtful of Apple, and now I get to complete my collection.
