Best way to learn Thai from your iPod?

I thought I wanted to try to learn the basics of Thai before my next visit, but busy with full time work and other hobbies my spare time is very limited.

I was thinking it would be great if I could learn Thai through lessons I could listen from my MP3, so I could listen to it every day in my car on my way to work and back.

Do you know if there is anything of this sort? I tried out a website called "Thaipod", which lets you download the first free lessons. However I didn't like it at all, I chose 'absolute beginner' and got lost very quickly as it got into complicated things before even teaching the basics "hello, thank you, yes, no etc.."

If you know any good mp3 thai lessons please share!
