Someone linked to this website a while back, but I can’t find it. It was a website where people could post the meanings to various songs. Quite interesting, really. But of course now I can’t find it!
Dunno if it’s the one you’re looking for specifically, but http://www.songfacts.com seems to fit the bill.
Close, but not it. This one seems to have a lot more “noise” in the comments than the other did.
