I know Youtube is Youtube but a lot of the comments were about the simple lyrics.
No matter what, people will always find something to complain about. (e.g., screams, too melodic, too simple, too catchy...) The bottom line is this: You cannot please everybody. Once you try to do that, it's a very slippery slope. We make the music we want to make. Period.
And in this case, these lyrics (simple or not) are completely relevant to me - and have a deep personal meaning behind them. As far as I'm concerned, that's all that matters.
Cheers,
