To answer my own question.........
A lot of electronic reggae sounds really good.
Normally I can see/understand how different musical genres have progressed over time, but it's pretty hard to see how reggae morphed into dancehall.... reggae was based on some pretty nuanced musicianship, and dancehall was based on some pretty crude electronics, without subtle timings and dynamics.
However, dancehall worked and created some good sounds. I just can't quite see it as part of the reggae story somehow!
