Start with the assumption that any music is copyright, and that by using or copying the music you are infringing on that copyright. Then see if your intended use fits into the exceptions.
You can make copies of music for yourself, as a backup.
Some music is released free of copyright, or with the right to make as many copies as you want.
There are "fair use" uses of music that allow you to use a piece of music.
etc. etc.
I don't know enough about the topic and your use to know if your intended use is covered by "fair use", but it's a safe bet that the owners and licencee of the music will be keeping control of that music pretty tight to preserve their cash cow.
I'm reaching into the dim dark recesses of my memory, but I believe someone recreated the "feel" of the music for their own spoof. Perhaps they released it to the public domain. Or, get a musically inclined friend to recreate the impression of the music.
