MuchLOUD was a heavy metal music channel in Canada. The first logo was the MuchMusic former logo spinning, then a really loud voice saying "MuchLOOOOUUUUDDDD!" and the logo shakes. On the former MuchMusic block, it only said "LOOOOOUUUUDDDD!". The second logo was the MuchMusic logo shining, until we here a little loud microphone sound when "LOUD" fades in. It is gone as of 2016, it is now Stingray Loud.
Trivia: The channel was real, but not the logos.
Scare Factor Edit
For the 1st logo: NIGHTMARE!!!!!!! The super loud voice, and the logo shaking will cause nightmares.
For the 2nd logo: Medium. The microphone sound might get to you.
