i stumbled across this as i was looking at my account. i bought an album of a japanese group right as it was released to the iTunes store Japan, and around the same time got a few free apps, etc. i must confess my memory isn't great but some of the page was kanji, the song titles were in english and were as expected.
everything seemed good. then later i looked on my iPhone, revealed hidden purchases, and it showed i had bought a U2 album. Now, i did not buy a U2 album, and my account seems normal, not hacked, every other detail seems correct, and my only explanation to myself is that somehow the SKU# of the japanese album was somehow attributed to a U2 purchase. On iTunes on my mac it shows the song titles totalling the correct purchase price, but the phone says U2. i am only mentioning this here to make a note of it, that i will be checking and refreshing the next few days to see if it works itself out, and watching for any fraud.
i am not alarmed yet nor ready to call or raise a ruckus, but i am old and listen to mostly old music from CDs. I mainly buy apps and they always have processed correctly. I bought the album, from Band-Maid, the week i think that David Bowie died so the world was kind of in turmoil. Again, I understand the complexity of global e-commerce networks and am assuming this will all sort itself out.
all that long winded explanation aside, why would one buy an album and hide it? To gift a family member? Surprise them that it is in the family share library? i think i understand this process, but i am typing this in so i can make sense of it later. i do see though that there could be a potential for fraud, although apple really seems to be on top of such things. Meticulous records are kept, we are talking about 12 US dollars, not a big deal, i watch my cards and apple account closely and my family and i talk and are aware of what we buy with our iTunes account. Just getting started really. But sometimes things get spidered and indexed and meaningful relationships in the data are detected. so i had a spare moment to type this. there is the evolving iTunes, iTunes match, music, beats, radio, all these elements coming together and if a human sees this and would like clarification i can give feedback.
