What were you expecting? It's the iTunes store.
Every single sensible person on the planet buys their songs directly from those who distribute or compose them or simply download them for free, iTunes is for braindead Apple users who don't know their way around the internet or are far too lazy to go out and buy a CD/DVD with high-quality tracks in a music store.
Your rant is stupid, this isn't about Apple.
If you haven't noticed, it's pretty hard to support jpop artists without paying a shitload, this is their way of saying oh, we do
have fans outside Japan and iTunes is the biggest platform to put our music on, let's do it so they don't pirate it instead.
Of course, you could
buy Kyarys new album if you want to pay $37
