As part of the transaction, HarbourView has acquired the publisher’s share of select compositions written by the Wolf Cousins collective, which includes hit songs released by Taylor Swift , Ariana Grande, the Weeknd and many more. Sources tell Variety the acquisition price is in the low nine figures, although reps for HarbourView declined comment.
