Track of the Week: Blaze, How Deep Is Your Love? (Asad Rizvi's Submerged Vocal Mix)
Asad Rizvi has proposed one answer for this question - fully submerged, thank you very much - but it's essential, in scientific circles, to obtain independent confirmation for your hypothesis.

A careful examination of the relevant variables (boogie-fat chuckling bassline, dreamy top line, falsetto backup vocals straight out of a Motown time capsule, and a lead vocal so mellifluous and true you'd follow it anywhere after five minutes) followed by exhaustive statistical analysis yielded a p value of Really Fucking Deep, confirming Mr. Rizvi's inital findings.

Long-term research plans include extensive field investigation as well as the analysis of mutational processes between wild-type ("original mix") and re-mixed variants.
