Desert Island iPod

I was thinking about what my desert island albums would be. But then I started thinking, as I think many who have started thinking about what albums they would bring to a desert island, it might be incredibly inpractical. Again, I'm sure everyone has thought of this, but the more you think about it, the less sense it makes to take ten albums with you on a plane or a boat or by whatever means of transportation.

1. What if there's no CD/record player on the island?
2. What if you only bring CD's but you find a turntable on the island?
2b. What if you can only find a casette player?
3. What if you can find a CD/record/cassete player but can't find an electrical outlet to plug it in to?
4. What if you're too busy hunting boars and escaping from the Others to listen to music?

Then it hit me: a Desert Island iPod. It would be a really expensive iPod with a battery that could last three years, even if you had it on 24/7. You wouldn't need an electrical outlet, and could listen to it while you hunt animals or run from scary black smoke monsters.

The only problem with the Desert Island iPod would be that, due to the massive battery and energy cost, the Desert Island iPod would only have room for ten albums.
