There are tons of bad albums, and bad songs, and bad bands.
There are tons of bad films, and bad TV shows. And bad actors, and bad directors, and bad writers.
There are tons of bad authors, and bad poets, and bad painters.
There are tons of bad EVERYTHING. That is what makes the exceptional seem...exceptional.
The only thing is that there is no accounting for taste. There are things that will appeal to person A that repulse person B, and vice versa.
So no one should object to the proposition that there are tons of bad things out there - in fact, MOST of the things out there are bad, to varying degrees. But people aren't always going to agree on which ones are good and which one are bad.
I guarantee that the few song by DT that I find absolutely repugnant have lots of fans here. I have no idea why they like those songs, because they are truly awful. But for whatever reason, those songs appeal to those people. And that's OK. That's what makes the world go 'round.
