Abiogenesis

According to a search, the 'lyrics' are: Wake up N equals r, f-p Wake up F, l, wake up N equals r, f-p, n-e, f-l, f-i, f-c, l, wake up N equals r, f-p, n-e, f-l, f-i, f-c, l, wake up N equals R F-p, n-e, f-l, f-i, n-c, l As the track is called Abiogenesis, it's possible these are amino acids in an RNA sequence (likely fictional) or some such thing.

The Drake equation states that:

N = R* fp ne fl fi fc L

where:

N = the number of civilizations in our galaxy with which communication might be possible;

and

R* = the average rate of star formation per year in our galaxy
fp = the fraction of those stars that have planets
ne = the average number of planets that can potentially support life per star that has planets
fℓ = the fraction of the above that actually go on to develop life at some point
fi = the fraction of the above that actually go on to develop intelligent life
fc = the fraction of civilizations that develop a technology that releases detectable signs of their existence into space
L = the length of time such civilizations release detectable signals into space.

btw, this equation was mentioned by Howard and detailed by Sheldon in the 20th episode of the second season of the television series The Big Bang Theory. Howard goes on to modify the terms in the equation to project the likelihood of a member of the group hooking up with a member of the opposite sex. He uses the "Wallowitz Coefficient" which equals neediness times dress size squared to achieve this.
