I subscribed to Apple Music today and I am downloading the music I like for offline download. They are not 5K. They must be 400-500 or less. I have 115GB left on my iPhone so that's not a problem. It will be like 5-6GB or so, maybe a bit more. Anyway, my question is if there's a drawback whatsoever to download my favorite 400-500 songs for offline listening.
