The song is about the shadow left behind by a broken heart, that moment when pain becomes emotional armor, mystery, and movement, turning sadness into a groovy, seductive dancefloor energy through a deep bass drop and sensual vocals. To the writers/producers, the track represents transforming heartbreak into something powerful, elegant, and magnetic: a reminder that even the darkest emotions can still have rhythm, beauty, and control.\",\"field_visibility\":{\"mood\":true,\"tags\":true,\"genre\":true,\"share\":true,\"play_count\":true,\"remixes\":true},\"genre\":\"Tech House\",\"isrc\":\"\",\"is_unlisted\":false,\"iswc\":\"\",\"license\":null,\"mood\":\"Sensual\",\"is_stream_gated\":false,\"stream_conditions\":null,\"allowed_api_keys\":null,\"is_download_gated\":false,\"download_conditions\":null,\"tags\":\"markcast,wedontknowu,corazonnegro,techhouse,spanish\",\"title\":\"Mark Cast, We Don't Know U - corazón negro\",\"duration\":151,\"audio_upload_id\":\"263ecd1a2d5da2fb48caa11a2b877740\",\"track_cid\":\"baeaaaiqsecuofuqpnrbomvjohebqta36mcj4gtnmpyigfhx4ewdofizotwtge\",\"preview_cid\":\"\",\"orig_file_cid\":\"baeaaaiqsectx2zbdh7f3yl7lf7w2zntjarig2gjmwwizheqigxa525ktfs4z4\",\"orig_filename\":\"Mark Cast, We Don't Know U - corazón negro.wav\",\"is_downloadable\":false,\"is_original_available\":false,\"is_playlist_upload\":false,\"ddex_release_ids\":null,\"ddex_app\":\"\",\"parental_warning_type\":null,\"bpm\":127,\"is_custom_bpm\":false,\"musical_key\":\"E minor\",\"is_custom_musical_key\":false,\"comments_disabled\":false,\"is_scheduled_release\":false,\"owner_id\":321158566,\"audio_analysis_error_count\":0,\"cover_art_sizes\":\"baeaaaiqseaemeqjcrxz2k2rsj3hfo4yw3635fzoiq7wxwe6vijvdv7bma6te6\"}}",
