How do i use music codes for custom stages?

[BriefCasey795]

Ok, I have PW's Stage Expansion 2.0 and EternalYoshi's Maxed Out SSS. and i want to have them have music. I know there are these codes, But, I dunno if they work w/ Expansion pack 2.0, and I don't know how to use them. Here are the codes i found in a topic on the help forum.

Sorry but you are not allowed to view spoiler contents.
