Free song distribution refers to the process of getting your music onto streaming platforms like Spotify, Apple Music, Amazon Music, and YouTube Music without paying upfront fees. Instead of hiring a label or paying heavy distribution charges, artists use platforms like A3Tunes to make their tracks available worldwide. The distributor handles licensing, metadata, and delivery to digital service providers (DSPs). Some services may charge a commission on royalties, while others keep it 100% free with added features. For independent artists, this opens the door to global exposure without breaking their budget.
