prolly only an artist would be able to answer
a new 12'' costs about 8-9€.
a 12'' digital download costs about 7€ (just visited a site which offers "high quality" mp3s but have never actually used one nor intend to in the near future , so correct me if i am wrong)
how much of the money go to artist, when buying a 12'' and how much when buying an mp3?
also: does an artist gain more money from vinyl or from mp3 from a single release availble to purchase both ways. does the artist get more than the label releasing his music?
