Vocafy lets you listen to 20,000+ Vocaloid and other synth voice songs, organized by producer, voicebank, and year. Every song plays from the original upload on YouTube or Niconico, never a reupload. Continuous playback with shuffle, loop, a sleep timer, and a radio mode that keeps going with related songs. Titles shown in romaji and English. Favorites work without an account.
