Decide Between Soundreef and SIAE
Soundreef is a for-profit competitor to SIAE. In Italy it operates through LEA (Liberi Editori e Autori), the non-profit entity legally entitled to collect on its behalf within Italian territory.
Soundreef is known for transparent, frequent reporting and a digital-first dashboard, and is popular with independent and modern songwriters. SIAE still has the broadest physical/event licensing footprint.
This is an either/or decision for the same rights. Picking the society that fits how your music actually earns (digital vs live/event) maximizes what you collect.
Registering the same works with both SIAE and Soundreef. This double-claim creates disputes — choose one mandate per right.
