iTunes is sticking around on Windows but will just be for audio books and podcasts? That’s absolutely bizarre.
(Music purchased on iTunes can be downloaded directly to the device without syncing, but you need to manually sync with your computer to transfer over music that you acquired elsewhere. Either that or you subscribe to the iTunes Match service assuming that sticks around)
Basically, in the PC version of these apps the main difference compared to Mac seems to be that Apple didn’t split Podcasts and Audibooks into separate apps. They’re just mushed into an app that’s weirdly called iTunes. I feel like they should have clumsily but less confusingly called it “Apple Podcasts and Audiobooks”
