It might sound ironic coming from someone who used to run a (small) dance pirate station, but pirate stations don't do much good for the dance industry.
If we had dance music on pirate stations everywhere, the format would be regarded as "the music pirate stations play" just like Caribbean music is now.
You know, from reading this, the way terrestrial is going now with only CHR, CHR/Rhythmic, AC, Sports, and AM simulcasts on the dial, I guess all the other formats will be "the music pirate stations play."
