Depends. LN Beats surfaces all music RSS feeds, even those uploaded to platform -- which you'll recognize because there will be one single 100% split in the boost PLUS the WL symbol in the upper right corner. No symbol means the feed is self-hosted and published by the artist, but sometimes you'll see Music Side Project (MSP) or RSS Blue symbols. Those are decentralized too in that the artist determines the splits and their value is not custodied.
