Even though J. Cole fans range from my age to 25 while Drake fans range from young as hell to old heads who don't wanna admit they like Drake?Depends on what you consider great.
I'm not a big Drake fun but it's easy to see why he's popular. He (or his team?) writes "safe", catchy lyrics that are easily digestible and the subject matter (haters/success/relationships with women) has a very strong appeal to teenagers-young adults, the most prominent consumers of mainstream music.
Like I said, I don't think much of him musically but I do think he is a great marketer at least.
I like Cole, but his fans piss me off
