My interpretation's been this: Adam Lambert states "My heart is a ghost town" because he's basically saying that his ability to love is still in place (as in a ghost town the buildings and other infrastructure elements are still in place), but there are only memories inhabiting his love (no current residents, just like in a ghost town). So, in a nutshell, he's still able to love, but currently he's not in love.
However, in a interview for AT40 dot com on April 22, 2015, he stated: "Chasing the original high. That’s the hook. I feel like we all do that on some way, whatever the original high is to you… The first time, for me, [when] I got onstage and that adrenaline rush, that kind of high”.
