While my favorite music genres are Celtic punk (including Aussie and Norway bands), 50s/60s Brubeck and oldies, I do enjoy some "Viking metal" videos occasionally. I won't be running out to buy CDs, or working out, but I like Amon Amarth's Twilight of the Thunder God and the band below. I hated my daughter's U.S. metal bands in the 1980s, but Viking metal is more like punk-metal.
