Because it's shallow music with pretensions of having deeper meaning behind it (expressing love to an unnamed partner or crush using cutesy, flowery, uninspired lyrics isn't a celebration of love, the only universal force that drives human activity more than fear. What it is is cliched, insincere bullshit).
Because it's generic and bland.
Because it's music composed specifically to appeal to the widest audience, not to express the passion or ideals of an individual.
Because most people only listen to it because the corporations who own the artists (and they do own them) spend millions of dollars popularizing them by plastering their faces on billboards and magazine articles, putting them on widely-viewed talk shows and using other methods of advertising to force their face and voice into the heads of millions of potential consumers.
Because, although a lot of it isn't necessarily terrible, most of it is mediocre and doesn't really deserve the attention it gets.
Because it takes attention away from talented individuals with real artistic potential.
Because it causes most people to think that it is the only kind of music worth listening to, creating a zeitgeist of aversion to anything artistically dynamic, slowing progress and sapping success away from much better artists.
