mp3s need meta tagging for podcasts

As I listen to increasingly more podcasts, one frustration I keep encountering occurs when I am listening to a podcast/radio show that runs for over 40 minutes, and I need to stop it in the middle. Then, if I've quit the player, I have to manually try and find the place where I stopped.

One simple solution would be to add timecodes and labels to the comments field, for instance:

0:00,"chapter 1",2:45,"chapter 2", etc.

And then players could support this information by allowing you to skip ahead by timecode within a single mp3.

It would also be nice if mp3 tags could be given temporary bookmarks -- so I could stop and bookmark it in my iPod and then resume it on my PC.

C'mon lazyweb ... make it happen!
