I've stopped tracking for discs mostly.
I figure the vast majority of people are listening with their mp3/media player. I know personally i haven't burned a show to audio CD's in at least 3 years, so I'm not really too worried about the people who still do. And if they do, they can split it up on their own, and have whatever sort of length to the discs they want. Most things i've taped end up being roughly 90 mins maybe slightly more, so it's like do you track it at 45mins + 45 mins, or just let someone do what they want if they want to use filler and put 75 mins on one, 15 mins on another and fill the end of the disc with a smaller recording?
Let everyone else decide what they want to do, I'm just providing the show.
