When Sam flips the power on at Flynn's, the jukebox immediately breathes life into the abandoned arcade. Newer TRON fans may be surprised to learn that high energy ballad blasting in Flynn's Arcade is actually a Top 40 hit from 1983. The song is Separate Ways (Worlds Apart) by the Steve Perry fronted rock band, Journey. Though Daft Punk scored the majority of TRON: Legacy's music, certain songs were used to create nostalgia for the early 1980's.
Here's the original Journey video. Take a few steps back from TRON's futuristic grid to enjoy the 80's hairstyles and air instruments.
