My mother used to play The Crusaders all the time, and there didn't seem to be anything special about their sound. They mostly created smooth jazz, and every now and then, they'd pepper in a singer (like Randy Crawford on the title) track, but it wasn't enough to command my attention as a youngster. As I got deeper and deeper into hip-hop, I appreciate the abundance of samples that could be found on smooth jazz records, and then as I got older, I came to appreciate the genius of Joe Sample (a member of the Crusaders) as a producer. But this record is perfect background music of chores around the house, or reading the paper on a Sunday morning. It also can border as the soundtrack for 70s porn, and ultimately, isn't that the kind of versatility you're looking for in your music?
