Oh I can think of n number of songs for Siddhima... I guess every romantic song would be just perfect for them... A couple of my favs would be:
1. Saansein maddham hain... from the movie Kasak... Thats just one too hot to handle song and I guess it would be perfect if the setting would be Riddhima trying to seduce Sid 😉
2. Kismat se tum... from Pukar... It isn't exactly a C night kind of song but it just suits them so well
3. Bahon ke darmiyan... from Khamoshi
4. Saanson ko saanson mein... from Hum Tum
5. Chup tum raho, chup hum rahein... from Iss Raat ki subah nahi... Its one of my favs.. Love this song to death..
6. Dekho naa... from Fanaa would also be good if the setting is on the similar lines (Rain n all 😉)
7. O re piya... from Aaja Nachle would be a great option...
8. Bavari piya ki.... from Babul... Thats another of my all time favourite songs...
9. Kuch khaas hai.. from Fashion... another song to die for...
10. Mar jawan... from Fashion... this one too would suit the scene perfectly....
Among main other favs for Siddhima would be Saiyyan and Teri Deewani by Kailash Kher.. As I said I could go on n on but these are some of my top favs I'd like to see on Siddhima in a romantic sequence... 😊
