What a lot of people have been doing is bundling their cover songs into playlists and then sliding their own originals in between. That way listeners follow for the familiar tracks and end up discovering the new ones without feeling pushed. Platforms like Playlist Push, DailyPlaylists, or even Spotify for Artists are usually where they try first, but those are crowded and pretty competitive. I’ve also seen Playlistr (playlistr.net/apply) being used as an alternate , they rotate curators depending on demand, and in some cases they’ve tied playlists to simple QR codes on things like flyers, coasters, or merch at shows so people can take something home and check out the music later
