2Pac is one of the most infamous figures in Hip-Hop history. Case in point? His Greatest Hits has spent a whopping 450 weeks on the Billboard 200 charts — that's more than eight and a half years.

That makes it the 4th-longest-charting rap album in history, after Eminem's Curtain Call: The Hits (607), Kendrick Lamar's good kid, m.A.A.d city (526), and Drake's Take Care (508), per Billboard.

In other Pac news, ROCK THE BELLS recently spoke with Digital Underground's Money-B, and he shared insight about the prolific rapper's work ethic.

"His work ethic is unlike anything that I've seen since," he remembered. "I know what work ethic looks like because he was super focused and he worked super hard. I've never seen anybody work that hard when it comes to writing songs and being laser-focused on what he wanted to do and how he wanted to get the most out of things. It was Shock G on the production side and 2Pac on the writing side and neither one of them would leave the studio until things were sounding exactly how we wanted them to sound."
