Radio station play lists, record sales, concerts and ticket sellers, etc. Many of these logs, play lists, etc. are not scientifically collected. In many instances, the licensing agencies attempt to collect as much information from a large source. This is part of the problem. Although major radio stations do provide an excellent representation of the primary play lists, they do not provide quality input relating special programs, weekend shows, or local events and festivals.
Many stations break away from normal programming on weekends.
Bluegrass, blues, gospel, and other forms of music which are not part of weekday programming are often aired regularly during non-prime time and weekends. Often agency logs are not kept for these programs and thus the artists represented during these programs do not receive their fair share of royalty payments. Record sale volume is provided through major distributors as well. Here again is another problem. The major distributors provide a service to the core commercial market.
