As I believe was mentioned upthread, MBD's last album was indeed supposed to be his last, because he wasn't making enough money off albums due to copying, but he ended up making way more than he anticipated. He pinned that on the fact that the album was much more Yeshivish/Chassidish (less modern) than his previous few albums, and therefore attracted a clientele who generally don't copy CDs. He therefore decided to put out another CD in the same style. This is the story that was going around a few years back.
