You realize any Joe Schmoe can annotate what he personally believes the meaning of a particular lyric is.
If you read any Kanye West lyrics on that site, they break down every line like it's some kind of literary divine intervention of pure brilliance by grasping at every straw possible.
That's because every Kanye West line literally is a literary divine intervention of pure brilliance, of course. Anyway, there is a verification system in place and you can also discuss the line through a commenting system. I usually find their annotations to be precise and correct.
Agree that's sometimes happens. The site also incentivizes every single word to be explained, which makes for some pretty mundane, very little explanations. But there are times where I just don't get the reference and someone's been kind enough to provide it.
