Note style used should be determined in the following order:
If the player has picked a custom note style and has enabled "Force Note Style", that note style will be used.
If a song specifies a custom note style, that note style will be used.
If the player has picked a custom note style and the song allows the default note style, that note style will be used.
If the song and player have not specified a note style to use, or if an element of the chosen note style is not available, use the default note style normal.
