Depending on intent and logic, both expressions could be right. If you choose to establish a connection between music and books, or, if you wish to herald that they (music and books) go in tandem then
Music and books makes/is/has/…
will be appropriate – just as:
Chicken and chips is good for lunch.
But, if the two matters are considered separate or separately, then a plural verb will suffice:
Music and books make/are/have/…
