The Umlaut is not a band name, but if it was, I would give it a very high rating. The umlaut (those two little dots) is a typographic symbol that conveys a doubled sound for a vowel. For example, "cooperate" should properly have an umlaut. Without the umlaut, it would more correctly be pronounced with 3 syllables (coop-e-rate) instead of the accepted four-syllable pronunciation (co-op-e-rate).
The umlaut is the recessive genetic disease of the heavy metal bloodline. It probably first appeared in the name Blue Öyster Cult. It then propagated to Mötley Crüe, Motörhead, Queensrÿche, and jumped genres to infect punk band Hüsker Dü. Hüsker Dü is the only name above where an umlaut might possibly be used correctly from a pronunciation standpoint. But pronunciation isn't the point--the point seems to be to look Viking or something. I love how Spin(..)al Tap parodied this by placing an umlaut over a consonant.
Any band with an umlaut in its name is going to get marked down heavily by me, unless it's an obvious parody. Mötley Crüe, what's wrong with just calling yourselves Motley Crew?
Blue Öyster Cult: 3
Mötley Crüe: 2.2
Queensrÿche: 1.5 (major pretentiousness going on here)
Hüsker Dü: 6.5
Spin(..)al Tap: 8.7 (good execution of multiple levels of parody)
