I don't know how reliable a source this is, but Tom is talking about how he especially likes "Lifeline" because it's the first song he sang after he was sober. I'm confused because I've seen AVA live since the release of I-Empire and he was drinking beer during the set. Did he do other drugs or something?
(Buzzworthy: What’s your favorite song off your new album, I-Empire?
Tom: I really like “Lifeline†a lot. It was the first song I sang after I was sober.)
