I download lots of Podcasts, but sometimes I don't want to listen to a whole one; I want some music instead. This is fine if I have the Podcast in AAC format, but most of them are MP3. I know I could convert them, then make them bookmarkable, and then run them to the spot I was in, but that's not very Mac like, is it?
My method is a bit of a hack, but it works, and makes sure I don't miss things.
Just pop up the info panel (Command-I) for the track you wish to 'pause,' and put the current track time as the start time. Remember to use a colon to seperate minutes and seconds, and a full stop for fractions of a second. When you return to this track later, it will start at the noted location. Now, this sounds like an ideal candidate for AppleScript, especially if a comment ("bookmarked"?) was added to make all your marked tracks easy to find. (I'm talking to you, Doug Adams!).
