You gotta give the guy his due. A 15 year run in any genre in any era is insane. Drake knows how to make hits, is willing and able to shift to whats hot, and the thing that I think really has helped him is he has stayed focused. He never veered off into other shyt to the point that music took a back seat. Thats the most surprising thing for me as I figured he would slide back into acting and try to Will Smith it. I dont think anybody can honestly say they say THIS coming.
Beyonce had a 15+ year run. Taylor Swift had a 15+ year run. Eminem had 15+ year run. Nas had a 15+ year run. Jay-Z had a 15+ year run. Kanye had a 15+ year run. Snoop had a 15+ year run. Ice Cube had a 15+ year run. LL Cool J had a 15+ year run. Lil Wayne had a 15+ year run. Dr. Dre had a 15+ year run.
I'm not discrediting Drake's run per say but I'm just pointing out that staying relevant for 15 years in music isn't as uncommon as you're making it out to be. Maintaining a run for 20 years is usually much harder.
Now, if you're arguing that Drake "ran the game" for 14 years, that's very dubious cause he was definitely in Wayne's shadow until Take Care dropped. Drake had tons of competition for the top spot in rap until 2015 imho. Also, due to the decline in newer rap stars, Drake's been "on top" more so because the Gen Z rappers are coming and going or literally dying before they can make it to the top.
