Song file used by BeatMania, a rhythm video game that uses a DJ interface as the controller; similar to a .BMS file, but designed for BeatMania controllers with 7 keys rather than 5 keys.
BME files are saved in a text format and are referenced during the playback of song. They contain the song title, artist name, genre, BPM, number of players, note positions, references to sound effect files, and other information.
Like BMS files, BME files are native to BeatMania, a console-based video game. However, they can be opened on a PC with StepMania.
