(hennemusic) Metallica's recent release of its full catalog on Spotify has negatively affected the group's album sales.
Based on the catalog's performance in previous years, album sales were 15% below expectations the week the titles were added to Spotify and 35% below expectations the following week. Sales were in line with expectations the week before the titles were added to Spotify, reports Billboard.biz.
Metallica sales had jumped 60% to 61% in the four-week period leading up to Christmas in both 2010 and 2011; in 2012 that four-week increase was just 27.2%. more on this story
