DVD players can play music CD's, because they were designed to be backwards-compatible.
Why is a DVD more preferrable than a CD?
A DVD is more preferable than CD for its higher storage capacity than CD. Generally, a CD can hold up to 700 MB whereas a DVD can hold up to 4.7 GB. DVD is not only superior than CD in storage capacity, but also it is superior in requirement.

A DVD requires a DVD combo drive or a DVD player which allows to read CDs as well as DVDs. Thus, a DVD is more preferable than a CD.
