omg! i just realized that i felt that way when i read your post!
again. i absolutely love that album, fave band etc...
also, i believe that most of the lyrics are deep. Hayley in general writes about real things so taht automatically makes people connect to them. so what if they're vague? that just makes room for interpretation, which i'm all for. Music is supposed to speak to you like that. and also, who cares if they have a few songs (whoa) that don't truely have a meaning. sometimes you just gotta let loose in some songs. it doesn't all have to be serious.
i could rant forever. my opinion is that both albums are good in their own way. they both achieved their purpose and there are somethings i like some i don't but that's the same with everyone...don't know what else to say so imma end.
