For labels nothing's adding up cause they ain't marketing sense
Fuck it..

from Kembe X – X Lyrics on Rap Genius

Meaning

Record labels are marketing hip hop music that promotes material wealth and extravagance, and Kembe is pointing out that they’re probably not making much money off of it since kids are more likely to go out and buy jewelry and clothes than CDs (which they can just download for free).

Also a bit of wordplay on sense/cents with the adding up money analogy
