Mia and Sebastian's Theme acts as the main theme to La La Land. It is first played by Seb, in the restaurant after he is tired of playing Christmas music. The theme is used repeatedly in the movie, including in Planetarium, Mia and Sebastian's Theme (Late for the Date), Epilogue, and The End. Mia is represented by the romantic part in the beginning, while Sebastian is the erratic jazzy part at the end.
