I'll add my endorsement. Pimsleur was the most enjoyable audio learning experience I've had while commuting, because I actually learned something that has kept with me.
They use spaced repetition and native accents. I hear what I should say in my mind when I want to say it instead of trying to think of words on paper I've learned. Of course, it has its limits (you don't learn to read or write), and only gets you the basics of a language, but it really helps you nail them in a way that makes you feel like you're naturally learning a language like a child does.
