So, hey, bump for some advice.

I'm slowly, slowly learning the language, mostly orally. Once I can decipher all kana reliably, I don't plan on actively learning more than the bare minimum of kanji, since I expect to use technology (and in my travels, my evil foreigner status) to make the rest of them magically go away.

So, a question, where could I find some good material to listen to during the very long car rides I have to take way too often to my taste?
Not lessons like Pimsleur that require your attention and advise you against doing more than one half-hour lesson everyday, I need something entirely in Japanese I can leave in the background for hours and ignore like a normal radio program, and that I don't need to fully understand to learn from.
I'm thinking audiobooks accessible to kids and stuff like that. Maybe podcasts that deal in mundane matters that don't require fancy words. Major bonus points if they are not anime drama CD.
It needs to be more or less easy to acquire, too!
Any ideas?
