You know what, as far as a list of pop songs goes, they are a pretty good representations of the pop songs that were somewhat original, catchy and at least not cut-worthy. I didn't look through the whole thing, but from the snipets that caught my eye, I dare say they selected a pretty decent swag of popular music that would be considered good by many.
I mean, c'mon guys, is a prog-forum ever going to be like wow this list rulez!
