And with podcast you can re-listen to it...

That's what I did. I quite like podcasts, since it lets me listen to Japanese while doing something else. In that sense, its useful, but you'll definately need to listen more than once since if your mind drifts, or you're doing something else, you'll not get the best out of it.

I think I used something like Japanesepod101...

I recommend using podcasts and audio learning, but it is a good idea to write and read too.
