These examples are from past projects that were custom made.  They are a good reference of what can be done (a lot!).  In a court of law I could be asked if a producer and or director requested for me to “copy” a song or make a similar song based on another artist.  Which could lead to legal troubles.  It’s much safer to give me a general genre request and even better to use my music as a reference.  Also some of these tracks’ previous contracts have expired, and are their themes are available again.
