I love Tupac! He sold over 75 million records worldwide, 
Oh Tupac! He's a rapper right? Wasn't he murdered?
He was and yes sadly. His album "All Eyez on Me" (1996) is the best one in my opinion.
What's a good song from that album? It's really sad that he died...
Monica is a great one. Shakur is consistently ranked as one of the greatest and most influential rappers of all time today.
