In the Tupac: Resurrection coffee table book you can see Pac's contract with Deathrow. Pac really wanted to get out of jail, so he signed a handwritten contract, agreeing to make 3 albums for Death Row Records....in exchange for Suge Knight posting $1.4 million bail to get Tupac out of prison while he awaited his appeal trial......so basically people say Pac signed a shitty contract so he could get the fuck out of jail......also, apparently, when Pac "died" (I put quotes bc I don't believe Pac is dead) he had no money and none of his assets were his, his Rolls Royce, Benz, Jag, house, were all under Death Row Records ownership,,,,this is why you'll hear Pac saying lyrics like:
"This is my prophecy, I gotta get paid"
"Can I get paid, can I get paid, can I muthafuckin get paid"
"you scream and go '2Pac' and I ain't stopin' till i'm well paid"
because DR Records weren't paying him properly.....anyway so maybe that is why people say Pac sold his soul to Suge Knight.
