NostrGram was a good app to find music, it had built in filters for Spotify, Tidal, and Apple Music (I mostly use Tidal from nostr:npub1sg6plzptd64u62a878hep2kev88swjh3tw00gjsfl8f237lmu63q0uf63m ). Sadly NostrGram not running anymore. Maybe nostr:npub12vkcxr0luzwp8e673v29eqjhrr7p9vqq8asav85swaepclllj09sylpugg or nostr:npub18m76awca3y37hkvuneavuw6pjj4525fw90necxmadrvjg0sdy6qsngq955 can build in music filters!
