This quote from Courtney Love's letter to recording artists summarizes the position of most artists:
Record companies have a 5% success rate. That means that 5% of all records released by major labels go gold or platinum. How do record companies get away with a 95% failure rate that would be totally unacceptable in any other business? Record companies keep almost all the profits. Recording artists get paid a tiny fraction of the money earned by their music. That allows record executives to be incredibly sloppy in running their companies and still create enormous amounts of cash for the corporations that own them. The royalty rates granted in every recording contract are very low to start with and then companies charge back every conceivable cost to an artist's royalty account. Artists pay for recording costs, video production costs, tour support, radio promotion, sales and marketing costs, packaging costs and any other cost the record company can subtract from their royalties. Record companies also reduce royalties by "forgetting" to report sales figure, miscalculating royalties and by preventing artists from auditing record company books.
