I have heard that there are such cards for songwriters too!sort of on the same topic ,
did you ever get into the principle of Eno's oblique statagy cards , not the actual cards but the idea behind them ?
you can make your own cards and follow on that idea ,
like if you get stuck with zero motivation,
pull a card from the deck that might say;
" do this track with out drums"
or another that might state;
" incorporate an unfamiliar instrument"
" only play the lower half of the keyboard"
just to give you a nudge in a different direction and break up that overly utilized recording formulas
Mutt Lang had Def Lepard record each note of a chord separately then mixed the notes in during a mix during Hysteria
great sound breaks up the mundane
Some of what I've read about was mainly for lyricist work.
