MusicPlasma
Providing a visual map from your favourite artists to others you may be interested in by genre and epoch, MusicPlasma is both visually pleasant and innovative. Without being bias in any obvious way I did question the fairness of a claim Elton John, The Rolling Stones and David Bowie are all considerably less popular artists than Norah Jones or Jethro Tull. See what you make of it all.
