To be fair to Blueprint, you can be a bit too close to see things objectively.

I think the band's quite good actually, I just find the way they mixed their song doesn't do it justice.

I also think that a good video can push a song a lot further, take "Call on me" by Eric Prydz. An awful remake but the video pushed sales through the roof. A good video puts images in your head which you remember every time you hear the song.
