Irving Azoff’s music rights firm has settled its five-year legal battle with the group that represents more 10,000 radio stations, ending a fight that threatened to undermine the 80-year-old arrangement under which artists are paid for commercial airplay.

The two sides also announced in a press release that a majority of commercial radio stations have agreed to a long-term license with GMR, which allows the settlement to take effect.

Azoff was able to obtain rights from a relative handful of songwriters whose songs had been performed by John Lennon, U2, Tom Petty and the Heartbreakers, and others. Those songs were deemed must-haves for radio catalogs, and GMR then sought significantly higher rates than its artists were receiving under ASCAP and BMI.
