Hello Reginald,

For licensing reasons (for title and melody) Band in a Box does not contain original songs. However, you can find suitable mgu and sgu files for many well-known songs in various sources on the Internet.
Some threads in the English forum deal with this, e.g." https://www.pgmusic.com/forums/ubbthreads.php?ubb=showflat&Number=618850".

You are right: Band in a Box automatically and randomly generates accompaniments based on the specified chord changes. So on the one hand they can sound new with each new click on "Generate and Play" (if you want to keep an accompaniment permanently, you can freeze the corresponding track by clicking on the "*" button) and on the other hand each style also interprets for example chord extensions like 6#9 differently.
