"The shows have been wonderful," the singer-songwriter says in his video blog. "I keep trying to remind myself that this is something I get to do rather than something I have to do."
Of course, one of his most popular songs is his smash single, 'Fireflies,' which, after all this time, is still fun to play. In fact, Adam says he's "grown to enjoy it the more we play it."
"The artist really feeds off the energy of the crowd and vice versa," he adds. "It's something I never thought I'd be able to experience in that way, so it might be my favorite song -- Fireflies."
