i mean this is nothing new with an arranger or Producer getting a taste on the publishing side, however when sampling and looping became part of the music vocabulary well you get an act like a Puffy who suddenly has publishing and he is called a Producer.

you get a Jennifer lopez who gets a co credit on a song with 11 other people.

darkchild is the king of this business dude has like his family on tracks and they split it up 4-5 ways.

then you got the business arrangement meaning say that Jam and lewis Jam was the one who did the main work in the studio terry may or may not play on said session however they are business partners and they split everything 50/50.

or like LA and Babyface face did the bulk of the songs and La may or may not contribute,but they were eastablished as partners.

i remember when Mint condition first came out and there first album they wrote the bulk of the tracks however everything went through Jam and Lewis's Perspective Publishing house.

established name and act gets the mark on the loot.

but sampling and looping has allowed for even more writers then ever before.
