Musicplasma is a rather Flash heavy online music search application, based around a very very cool music association feature. Enter in a favourite artist and it will come back with a selection of artists which are similar.
It actually works quite well, and what’s more also links seamlessly to Amazon’s musicsampler feature so you can listen to sample tracks of the artists automatically.
‘The closer the artists are, musically speaking, the closer from each other [sic] they will be displayed on screen.’
