The content itself contains a lot of mistakes in it, that makes clicking to replace a song part fail without finding a file.
Just to name one - Blues 1 (SONGS\165DA150\9EE9EE10.BBS) doesn’t open any of the fills of part 1 (though everything else works fine!). I cannot fix it properly, as BBS file format is obscured. Opening the file in hex editor though, reveal absolute paths are stored there. They are probably leading to MIDI files on the local machine Goran himself used to pack the content. But it looks like the song was later reviewed, and other file paths are stored for the parts that fail to open.
