Hey guys, I just found a nice free metronome download and now that I have that, I would like to know what are some standard (and unique I guess as well) number of beats per minute (BPM)?

As of now I am just playing at 200. If you could suggest common BPM's per subcategory of metal, that would be awesome (although I understand the BPM can change several times throughout the course of 1 song).

Thanks in advance.
