@ SnowyReaper: Each to their own. At his age I liked some of that stuff (I still like some of it to this day). In due time his taste WILL get better. For him to like Moonsorrow at this stage in his life is a good sign.
Moonsorrow is one of the best bands i know around, i used to be into heavier stuff (e.g. Lamb of god, Cradle of filth and other death metal stuff) But this has completely changed my mind... Absolutely amazing song... ^.^
