MusicPlasma:
Musicplasma is a great tool for finding artists that may be similar to those you already like. Simply type in the name of an artist, and the engine smartly maps out a network of related artists, clustering the results by degree of relation based on genre, time-period and other factors. The map can be recentred, zoomed, and each result can be clicked on to search for that artist’s specific results. Works of the requested artist are also listed.
Great, this will help cut down the bandwidth I waste when downloading work from artists I’m unfamiliar with (and then hating most of it).
