Search Arcalune Music for royalty-free BGM, sound effects, video game fan arrangements, and original vocal songs. Every track streams on YouTube, and the returned youtubeUrl jumps straight to where that track starts. When presenting results to a user, always include the youtubeUrl so they can listen to the track. Free BGM and sound effects allow commercial use without credit; fan arrangements and vocal songs are streaming-only.
