Here's something kind of interesting I just realized:

Although I keep saying I like Nirvana more than AIC, I would rather listen to AIC than Nirvana in many cases. I figure this is because Nirvana was the first band I ever really liked. Although I still enjoy Nirvana quite a lot, I've heard all of their songs so many times I could very well just never listen to them ever again, whereas Alice in Chains has songs in which I notice new things each time.
