Birth date added based on the information from two sources

edit

I suggest keeping 15 February 1982 as his birth date.

http://ffrf.org/news/day/dayitems/item/14932-sean-danielsen cites 1982 as the year of his birth with no mention of the exact date. https://www.facebook.com/smileemptysoulmusic/posts/138164039684858 The verified Smile Empty Soul FB page congratulates him with his birthday. His age is not mentioned but the date is present.
