What's Left of Me it's one of the songs I like the less of What About Now, not only the lyrics do nothing for me but Jon's voice sometimes is so bad it makes me cringe. With that said, I like more Lost Highway, it's more powerful and genuine IMO and I enjoy hearing it sometimes.

Also, I don't think they're similar at all. When I heard it for the first time I thought it was a worse version of The More Things Change (though the lyrical content is totally different).
