Deputy Assistant Attorney General Renata B. Hesse, a former Google lawyer, issued two key recommendations. The first is that any of the performance rights organizations PROs — ASCAP, BMI, or SESAC—must license 100% of a song for public performance no matter what percentage of the song the PRO legitimately represents. Historically, when songwriters collaborate who are signatories to different PROs (which has happened thousands of times to produce songs you love), the associated PROs co-manage the rights so that all parties receive royalties accordingly.
