There are several types of pop-punk. An early type of pop-punk was developed right after Punk rock became popular in the late 1970s. Most of this kind of music is very much like Punk rock, but it features things from other kinds of music like pop music and older rock music, and country music, so different people can enjoy it. Some people call the Ramones a pop-punk band. The Ramones were a band from the United States.
