I like the seriousness. I like the elaborate storytelling and imagery, and how the lyrics are delivered in an easily digested, accessible way.
I used to be huge into emo.. the quiet to loud dynamics blew me away at the time. But now the last thing I wanna hear is someone yelling off the top of his lungs about heartbreak.
Songs about a woman who has done you wrong or unrequited love are the last thing I wanna hear now in general.
