What? So Rude Boy isn't pop reggae? and Katy Perry and Lady Gaga's anthems aren't Pop AC or Dance music? I get your argument. I believe it's categorically incorrect, though. Just because songs are popular does NOT mean that they shed whatever roots they had prior. The SONG is popular, not the artist. Hence why it's a rotation of different artists falling under the pop umbrella. Any artist can be pop. The actual content of the song is interchangeable. Could be Latin influenced, could be r+b, could be flat out blues. Hell, it could be opera. If it was popular, it would technically be a pop song.
I get your point but I disagree. I don't think that as soon as a song become popular it can be tagged as pop. When I think of pop I think of Britney Spears and people like her. And what about "Pop punk" artist that are not popular?
I know this probably makes no sense and I seem like an idiot but as I said before I'm not exactly sober right now.
