My attitude toward this sort of thing is that, if parents are paying for formal instruction, then students should receive something they can't get elsewhere. There are lots of publications with pop arrangements that students can play music from on their own.
That said, it's important for students to pursue their own musical interests. If students are captivated by the sound of hard-rock and metal, find music that shares influences with that style. For example, a lot of metal artists use eastern modalities and harmonies in order to make their music sound exotic to their western audience. Find some repertoire with an arabic or moorish flair, and leave it to the student to connect the dots. For students interested in southern or blues-based rock, try to open them up to some real blues (or even ragtime or some showtunes).
In general, try to spin it to your (and their) advantage by teaching them to use their musical interests as a springboard to expand their musical horizon. Just don't tell them that that's what you're doing ;-)
Hope that's helpful.
