JPOP and POP are completely different. They obviously are both in different languages but JPOP does not use swear words a lot. Pop music usually has profanities. You can also tell a huge difference in the effort of their music videos. For one, JPOP focuses on giving a nice visual type of music video depending on their budget for it. Pop videos look more like a bunch of random clips put together but shot on an iphone unless it is a huge celebrities music video. Now for the meaning of Pop songs-it really depends on which kind of song you choose because not every song has a nice deep mening to it. Same with JPOP.
