So the "Dickbuttunes = WIN" release was a sham (even *I* wouldn't go that far. I guess... 
). However, the meme based April Fool's release is *NOT* a sham. Chiptunes = #SrsBsns (Serious Business) features 22 new tracks based on/referencing 22 different memes by the following artists:
Glenntai
coda
YZYX
Here Between You Me
Theory of N
SingkongBalado
Professor Shyguy
Maxo
James Landino
Urizen
an0va
watashimo
1000 Needles
K.O.M.H.
Sam Mulligan
Shyabeetus
Together We Are Robots
8 Bit Jin
Dj McGRANAMAN
Michael Zucker
Extent of the Ham (aka Extent of the Jam)
D&D Sluggers
Why? Because Chiptunes = Serious Business, duh. 8-)
