Produced by the award-winning musician Gopi Sunder, Bangalore Days' upbeat soundtrack is fitting for a film all about family. On "Aethu Kari Raavilum", acoustic guitars blend seamlessly with backing tablas while Hachiran and Vijay Yesudas croon in a smooth, relaxed tone. Then there's the thundering percussion and triumphant chorus of Yesudas, Sachin Warrier and Divya S. Menon's "Maangalyam" and the sunny, chiming guitar riffs and pop rhythm of Siddharth Menon's "Thumbi Penne". Sunder crafts a wide variety of sounds while remaining true to the film's feel-good heart.
