They put out lots more songs along this lines of this love. They put out next to nothing like Harder to Breathe. But HtB was okay, It wasn't amazing or anything. I never got the extreme praise of their very first album really.
Harder to Breathe is definitely their best song. Their second album had more than a few that I liked on it though, like Makes Me Wonder and Wake Up Call. I liked Misery when it came out too. I can listen to almost all of the album V without having many complaints as well.
