It is without a doubt classic rock. (60's-80's)
There is no way tracks from Kanye West, or even sick underground artist will have the longevity that bands like The Rolling stones, Boston, Led Zep (specifically stairway to heaven) have had and still continue to have.
Just made me think because Kanye West mentioned how he was comparing his music to sick classic rock tracks and he said wanted people to listen to his music for years/decades to come. What a joke, almost all rap and rock these days has a catchy beat and no substance.
Classic rock, FTW.
