"Hackers and Painters" is an anagram for both:

"Rihanna's Track's Deep"

AND

"Rihanna's reptd. "cakes"

That in turn can be adjusted to ==>

"Rihanna's reptd. "cake cake" ==>

"Rihanna's repeatd. cake "C+K/3+11/14/N/14/a,d"

"Da Rihanna's repeatd. cake" ==>

"Da Rihanna rep(Es)atd. cake" ==>

"Da Rihanna repeated cake" ==>

"A Rihanna repeated cake "d/4/four/for u"

"A Rihanna repeated "cake" for U/.edU/.edU/.edU/.edU" etc. ... pretty much like the song's chorus.

"Cake" in turn turns into "E+C"-A-K" or "Hak" ...

"Cake" is repeated 15 times in the song in a

4/ 4/ 4/ 3 grid format

The last "3" could be viewed as a "c" which added to the "Hak" would make it "Hack" ... the remaining three "4s" multiplied together = 64.

"Cake" in the song lyrics thus becomes "Hack 64"

Furthermore ... a,c = 1,3/"13"/"m" ...

... and "H" = "8" ... "K 64 M8" aka early IBM Big Blue chess experiments?
