"Ambitionz Az A Ridah," from All Eyez On Me (1996)
If you were worried about the direction 2Pac's music might take after he signed with Suge Knight and Death Row Records in 1995, you stopped worrying about five seconds into the intro track on All Eyez On Me when the song's producer Daz Dillinger dropped an aggressive West Coast production that helped 'Pac spell out his intentions for the rest of the album. He was a rebel with a cause on this intro as he let out all of the pent-up frustration he'd stored away during a 1995 prison stint.
"U Got A Problem?" from Back for the First Time (2000)
Anyone who thought Luda was just another gimmicky rapper trying to make a quick buck off the success of his hit single, "What's Your Fantasy," thought otherwise when they pressed play on BFTFT and heard the ATL rapper go off here over a thumping production from then-unknown producer Bangladesh. And just for the record: We had absolutely no problem with him doing it.
