I agree with Peter the Viking; listening to internet radio such a AM has opened up new music to me, and I have bought more CDs as a result than I would otherwise. Most music radio over here in the UK is unlistenable for my tastes, so internet radio has been great.
The RIAA has made a big mistake here; their claims that internet radio and MP3 are killing their industry are wrong. It is their pushing of so much mediocre music that is doing that (at least in the UK).
I think I will be paying the $5 though.
