iTunes has many, many issues, but here is one that has been around for a long time... perhaps since the introduction of podcast subscriptions in iTunes.
In iTunes (under Mac or Windows), you can subscribe to something called a "podcast". Wikipedia describes a podcast this way:
A podcast is a type of digital media consisting of an episodic series of audio files subscribed to and downloaded through web syndication or streamed online to a computer or mobile device.
Podcasts are shown in iTunes in a folder-style fashion. There is a row for each subscription and underneath each is one row for every episode:
Some of these episodes are large (particularly for video podcasts), so I will sometimes delete an episode after I'm finished with it. If you click on the episode and hit your "Delete" (or "Del" for you Windows users) key, you'll see a message like this:
I always do a bit of a double-take at this message and have to verify that I selected the right thing to delete. iTunes is here referring to a podcast episode as a "podcast". Okay, well... what does iTunes say if you want to actually delete the podcast subscription itself? Well, it says this:
Here, it refers to the subscription as the podcast and refers to individual episodes as "episodes". This seems proper to me, and the former message seems wrong. I think this could be fixed by simply changing the word "podcast" to "episode" in the first confirmation message above: "Are you sure you want to delete the selected episode from your iTunes library? This episode will also be deleted from .....".
Apple, please fix that.
