Maybe it's something to do with a familiar smell, like the almost-imperceptible aroma of slightly overheating electronic components.
Maybe it's the potpourri of disinfectant, sweat, and the metallic scent of tokens, mixed with the cacophony of arcade sounds.
Maybe it's the multisensory kinesthesia of Happy Days reruns on the TV, Bard's Tale on the C64, and a high school art project.
Each song is the soundtrack to a 3-minute time capsule of a forgotten memory.
