Hello download, I believe you made a mistake in undoing the change I made last night to the Deanta article. According to Wikipedia guidelines you cited: "Some acceptable links include those that contain further research that is accurate and on-topic, information that could not be added to the article for reasons such as copyright or amount of detail." 

 irishtune.info is nothing if not "further research that is accurate and on-topic," and it represents a complex system of navigable links with solid research about the contents of that Deanta album that cannot be represented by simple quotation in the article. It is unique research that has not been duplicated by anyone else in the world. I suggest reading a bit further on the page I linked to. 

 I will restore the link so you can reconsider this.
