The bubble sound and music have separate check-boxes. You will be able to check either, both, or none.
Whether the default position should be "Both" is another discussion (but not for this group
)
And just to drive home what Cliff just said - What we are talking about here is the DEFAULT position of the checkboxes, not the fact that music capabilities will be available (they will.) The only question is what the user hears the VERY FIRST time he starts up MA3, before he has pointed the program to any of his own music or even looked at the user interface. If the user doesn't like my choice, he can simply press the "M" key and it's gone (and won't ever come back unless the "M" key is pressed again or the checkbox is marked in the user interface).
