"Pirated" goes very well with Radio. As, if you copied radio to a CD or Cassette, it was referred to as pirated. Keywords in .fm typically don't sell well, if at all. However, I think Pirate.fm sounds fantastic and has the potential for resale, and quite bit of potential for development.
I own Religion.fm/.am for about 2 years now - Im still holding, with very few/little offers. I would expect yours to be in the same range. Sounds great - but without development, your probably out of luck.
