Well it is supposed to wrap up the first ten years of Excalion.
They also had some bad feedback about their previous videos for Waterlines (which were made with no budget at all) and they decided that if they will make a video it has to be really good and a pro video so I believe it will be something special.
Since it is also done afterwards it is not for promotion but just a special extra.
And yes Enter a Life is one heck of a catchy song
I just love the crazy drum stuff in the intro and the vocals. The solos are also amazing.
Yet I have to say that even in all it's greatness it is maybe the weakest song on the album.
