I don't think I had even heard November rain before, at least not in full.
It was nice enough, loved the ending but not something I am planning to add to my playlist.
Stairway gets my vote, I like the slow build up as it progresses, going from slow ballad to more of a rock song.
That said, if I have to put a vote to a long rock epic I would go with Kashmir, Hotel California or if I have a lot of time to spare Shine On You Crazy Diamond
