Here's the case. As someone earlier in the thread suggested, I'm not sure that you can come up with a better five-tool player in his genre.
Song-writing
I don't know how in the world you can possibly rank song-writers, although historically Dylan probably goes down as the GOAT, with all due respect to John and Paul. Prince is in there somewhere, though. We could do nothing but list the songs for other people that's he's put together and put together a HOF song-writing career. From the age of 19, he wrote some of the most iconic songs of the last 30+ years.
Musicality
As I've stated before, he played all 27 instruments on his first album at 19. He's a Top 10 all-time guitarist and he played other instruments better than people who get paid to play them. He might rank No.1 in musicality.
Performance
He's the Jagger of his generation. Along with MJ, you're talking about a Top 2 showman from 1979-to-now. If I'm doing a Mount Rushmore of all-time performers.
I'd say MJ, Prince, Jagger and James Brown.
Longevity
Dropped a HOF album at 19 and sold two million copies of an album in his 40s. Still, for almost 40 years. he made 40 album and did something like 25+ world tours with nothing but huge sellouts. He died incredibly relevant, even if some in this thread weren't the ones he was relevant with.
Sexual Power
If we're going Mount Rushmore here, he's on the list with David Bowie and two other dudes that aren't Bowie and Prince. Just call it Mount Rush. Maybe throw Marvin on the list.
Again, if you're thinking in 100 years, this guy won't be at the forefront of this era's music discussion, I just think you're crazy.
