Background music

[Mac Consult SRL]

I have a question, how to put background music?, the play command
performs function but the amount of memory necesary is too big.   Is
there any way to keep he music playing while the user interacts with the
"title", this feature is available in AMT (extinct) and iShell.  BTW I
work with Mac.
