dualology 

Combination of three songs when you really only have two. They combine to make a trilogy, but really just a dual + ology.

The group The Hippy and The Titan combined three songs to make one, but really only combined two. They realized they had made a dualology.

Dealiology 

Dealiology was created by the likes of Austin Heath, a local musician from Buffalo, NY. With a bit of imagination, Austin created a religion for fellow musician and friend, Alex Deal. This, however, started as a joke, but has sophisticated itself into this religion:

"I believe wholeheartedly in the power of the deity of eighties metal, Alex Deal, and that the effects of this power may make ordinary men saints of a low moral style. All the impossible is possible when you believe!" ~Austin Heath

When other religions may confuse, offend, or fail you, Dealiology will always deliver!
