Deletion of List of heavy metal bands

Comment: The arguments that a category is better than a list should be discounted per ; the remaining arguments to delete are that it is redundant to other lists or consists of original research, which can be solved by editing or merging, rather than by deletion. But I don't think a merge is warranted here; this is a good combination article of a list of early influential bands in the genre and a list of sub-lists for the later and more numerous bands in various sub-genres. This is pretty much exactly the type of information I would expect to see in a "List of heavy metal bands" article. Whether it is called "original movement" or something else, the well-sourced heavy metal music article seems to support the idea of an "early movement" of heavy metal bands in the 1960s and early-to-mid 1970s, before the genre started to be influenced by punk and newer styles of rock, and before heavy metal truly entered the mainstream and started spawning off its own sub-genres; it seems that the formation of Motörhead in 1975 is a defining moment here. I think the split into separate tables for each letter of the alphabet is unnecessary; the list isn't so long that it needs to split this way, and in fact might be better sorted chronlogically rather than alphabetically. Another thing that appears to make this different than the list in traditional heavy metal is that the list in that article seems to include newer bands which play in the ''style'' of traditional heavy metal, as opposed to the first half of this list which is limited to bands which were influential in the ''formation'' of the genre
