Pop punk
Some people who like 1970s punk rock or 1980s hardcore punk do not like pop-punk. The 1970s punk rock or 1980s hardcore punk was usually angry, rebellious protest music. In contrast, 2000s pop-punk songs are nicer and lighter. Some people think 2000s pop-punk is too commercialized and nothing like the older punk music from the 1970s and 1980s.
