If the question is asking about Meshuggah, the Swedish experimental band, then the answer lies in the opinion of the asker. Whether or not their music is Satanic, or if Satanic is even a genre of music, is up to the asker to decide.
As the previous answer explains, "meshuga" is also a Yiddish (Hebrew) word. "Meshuga", "Meshugge", and other spellings are all slang words for "crazy."

Meshuggah is more like a serie of depressed & quite angry internal dialogues and essays of the shortcomings of ones "self" and it's relation to reality. Samples :
I (I 2004 EP)
This is an anomaly. Disabled. What is true? / Not destined for incarceration, I crave my nothingness
Sane (Chaosphere 1998)
Come and hear my twisted lies, the way I bend and falsify
A master of deception, user of an untrue smile
A rapist of the truth, adapting it to fit my cause
I'm the human lie, a sad composition of all things vile
This spiteful snake (Obzen 2008)
Reality - this spiteful snake, / Rearing its ugly head / Venom dripping from its grin / As it tosses yet another obstacle in our way
If given a thousand years to collect, / To process, to portray / We could never encompass the voracity / Of one single day

In the satanic bible they have a character which is the evil twin of Messiah. Cleverly named, Hossiah.
The Penny Auctions during the Great Depression were where farmers got together, preformed satanic rituals, and then got really drunk. After several drinks, they barfed into a barrel, then mixed it with their alcohol-saturated piss. They would sell cups of it for a penny each.
