I quite like 'Gambler'. Half the score is background music, credited to Sachin Dev Burman but with plenty due to Rahul Dev... hard to go wrong with that. All the instrumentals are ace, possessing a mod, groovy vibe; upbeat and bouncy ('Title Music'), jazzy and cool ('Gambler As Trumpeter'), laid back and European sounding ('Gambler's Dilemma'), funky and wild ('Gambler in Danger')...
The songs are nice as well, poppy and pleasant, if not spectacular. 'Churi Nahin Ye Mera Dil' would be my pick if I had to choose one.
