There is more information here than anyone could possibly wish to take on board, but as bedside browsing, this is an excellent tome. The metal lists at the end are worth the cover price by themselves. The Best of Blipcore, one of the more obscure elements in the list of metals, lists three "songs", the shortest of which is Micro-E! by Wehrmacht, which lasts for 0.1 of a second. Incidentally, this book does have an index which features multiple entries for Spandex. But not for Spinal Tap.
