You don't even have to stream. At any given morning before leaving my house I have around 20 podcasts preloaded. Assuming you spend 5 hours a day listening to podcast at 2x speed, and 1mb per minute for the audio, that's still only 600mb. Up to to 1GB to give yourself some options. Realistically, people listen closer to 2-3 hours a day, and even day, you can preload for a whole week using only 2GB of storage.
