I don't want to be connected to the Internet all the time, yet still listen to music? Is that not a good enough reason?

And contrary to what many seem to think, cellular data is not always available and data caps are still a thing.

If I sound pissed off, that's because I am. I've seen an ever increasing number of comments like yours that just dismiss things because they don't see the value to them. They then phrase their dismissal as an innocent question (which, honestly, comes across as very condescending).

I understand your point, but a question will be why not just loading your smartphone with mp3 files. In this case, you don't need internet connection (if this is the only the reason) and you don't need a separate device.
