I don't have unlimited data, so if I'm not somewhere with Wifi, streaming ain't an option. It's much more satisfying to own my music anyway, though I feel like I'm one of the few people in the world who still buys music.
It's just that since I primarily use my iPod, iTunes is still automatically the most convenient storefront for me since I don't have to deal with downloading and importing MP3's into it. Even if the software itself is...well, iTunes.
I'm kinda confused by that, actually. Yes, iTunes is basically being replaced by Apple Music...but not on Windows, I think? For now? And I think you'll still be able to purchase music on Apple Music but don't quote me on it.
