Which is correct: "What kind of CDs" or "What kinds of CDs"?

Is it correct to say:

What kind of CDs do you have?

What kinds of CDs do you have?

Solution 1:

I would say it depends on if you're anticipating a singular or plural answer.

If you're asking if someone has read-write or read-only CDs, what kind would be a sensible question.

If you're curious about the various genres the person has in their music collection, what kinds is a better question to ask.
