When Does Rock Become Classic Rock? [POLL]

What is Classic Rock? That's a good question that almost everyone has their own opinion on.

Some would classify classic rock as 60's, some would say 70's and 80's, but we are thinking that if it 15 years or older... it's "Classic".

Is Nirvana Classic Rock? Kurt Cobain has been dead almost 20 years.

What about "Jeremy" from Pearl Jam, or "When I Come Around" from Green Day? Would you consider these songs "Classic Rock"?

Let me know what you think by taking this poll and leaving a comment:

(The whole debate reminds me of that song '1985' by Bowling for Soup – so I included it for your viewing pleasure here.)
