Group is second-largest U.S. radio company.

Radio & Records has “temporarily suspended” all monitored Cumulus Media stations from all of its chart panels, the trade publication said in a notice on its Web site late last week. R&R has also dropped all Cumulus Indicator stations -- outlets not monitored by Mediabase that had provided airplay reports which fueled the publication's Indicator charts.

The moves follows a decision by Cumulus to no longer report music adds or playlists to any of the trade press.

The reported adds and playlists from Cumulus, and from many other radio groups, are crucial to the compilation of weekly most added tallies and charts for publications that still rely on such station reporting.

Cumulus’ change does not affect any Billboard Radio Monitor charts or features, which are based exclusively on electronic monitoring of actual station broadcasts by Nielsen-BDS, rather than reported play provided by the station.

Billboard Radio Monitor has for years tallied station support of new music via Airplay Adds which is based on monitored spin thresholds reached by new songs on stations.

Cumulus Media is the second-largest U.S. radio company based on station count. Pending closing of announced acquisitions, the company directly and through its investment in Cumulus Media Partners, will own and operate 343 radio stations in 67 markets.

Dickey did not respond to Monitor's request for comment this week by a midday deadline.
