Listen to us using Last FM or Spotify!
Today I've just launched page here where we describe how to tune in to Radio Rivendell using Last FM and Spotify, both are modern streaming services featuring both commercial and non-commercial alternatives. We've been recording everything we play to Last FM since May last year and we've setup a playlist on Spotify where there are five days(!) of fantasy music featuring both soundtracks from movies and games.
This is the perfect alternative to the situations where you cannot use your computer to tune in. Both Last FM and Spotify have iphone and Android apps available.
