Encyclopaedia Metallum is a user-driven database online since 2002 with over of over 83000 bands listed, over 209000 members and sortable by various search criteria including genre, country and lyrical theme, offering band and musician information and discography, over 63000 album reviews and an active discussion forum. Music Might is a database established by Garry Sharpe-Young in 2001 and online since 2008, offering very in-depth biographical information for an extensive number of metal and rock bands. Spirit of Metal is a user-driven database online since 2003 with over 67000 bands listed, offering band information and discography, reviews, a discussion forum, multimedia features and more, and is available in eight languages. The respective focuses of these three websites are distinct but still similar, and although some sort of merger or collaborative relationship would make excellent business sense it’s not mind-blowing that it hasn’t occurred.
However, beyond these three websites there’s also Underground Metal with over 12400 bands listed (active), Archaic Magazine with over 11900 bands listed (inactive), Metal Music Archives with over 10700 bands listed (active), Metal Storm with over 6700 bands listed (active), Librarius Metallicus with over 4100 bands listed (inactive), About.com with over 4000 bands listed (active), Metal Carnage with over 3100 bands listed (inactive), Metal Bite with over 3100 bands listed (inactive), Dark Soul VII with over 2900 bands listed (active), BNR Metal Pages with over 2900 bands listed (active), METALSITES.net with over 2400 bands listed (inactive), Brutal Metal with over 1000 bands listed (somewhat active), Metal From Finland with over 700 bands listed (somewhat active), Metally with over 700 bands listed (inactive) and Heavy Metal Bible with over 320 bands listed (inactive).
May of these websites possess other features beyond their band database, for example the BNR Metal Pages has shifted towards a more opinion-based review format based on the apparently well-respected style and musical preference of its owner Brian Russ. About half of these websites are still actively being updated, and none of them are so old that websites like Encyclopaedia Metallum weren’t already around when they got started. It takes a lots of time and effort to compile and maintain a band database, so my question is, why bother creating more? Two conclusions seem inevitable: there’s lots of redundancy and inefficiency in the online metal scene, and at the same time, metal listeners care a lot about the music and are willing to devote significant time and effort to supporting it.
Oh and I almost forgot, if you want to inspect plain lists of metal bands, you can always check out Metal Bands List, a website devoted to listing the names of all metal bands, or for $22.00 you could purchase the hardcover book All Known Metal Bands which consists of nothing but a list of over 50000 metal band names (presumably, at that price, in alphabetical order).
