What I was thinking when making this thread are songs that I didn't care about until I experienced them in a live context, but it can also apply to songs changed up in live performances for the better. Take it however you want. I didn't care that much about "Silhouette" when I got Thrice's The Artist in the Ambulance, but it's easily one of my favorite live songs. The heavy parts sound so awesome in that context. More recently, I liked "Making the Most of the Night" well enough, just like literally everything on Emotion, but it wasn't like a highlight for me or anything. It was one of the highlights when I saw Carly Rae Jepsen last month, though. That chorus sounded great.
