I want to add music that will play through layout 1-5 and on the 6th to change.
I only found out how to add music to 1 layout so far...
the music does not stop unless you tell him to, so if you restart the music on start of layout, that may be your issue.

Aphrodite is correct.
don't put restart layout on the other layout so that the music will continue playing. and on the 6th layout, stop the music by tag and start playing the new music on the 6th layout
