Hi All,
One or two years ago we had the same discussion on this forum.
Styles contain small fragments of songs and are NO songs themselves.
As stated before : Yamaha did NOT invent SAMBA, CHA, R&R, Blues or any other kind of music.
YAMAHA wrote the OS (= software) in which styles can be created or converted ..... sure, this OS has copyrights but styles are just input-data or output-data of the OS.
