There is some evidence that much as we are wired for language, and much as language is part and parcel of our humanity, music may also be coded in our neurobiology. Brain imaging suggests that the way we process musical "grammar" is akin to how we process language - the circuits overlap, the patterns mix together, language and music intertwine.
So our love of music may have something to do with our ear for the prosody - the beat and rhythm and tempo and pitch - of language. Oddly enough, we are not the only animals to enjoy a beat even though we are the only species with true generative language. Snowball the dancing cockatoo's rhythmic dancing to the Backstreet Boys' suggests that although other species may not have the best musical taste, they might share the joy of moving their bodies to a tune. Before Snowball's example emerged, it was considered to be a uniquely human behavior.
Although perhaps not one scientists are all that good at, as the following video illustrates nicely.
