for me it is "madhosh dil ki dhadhkan......" from the movie "jab pyar kisi se hota hai..." starer Salman Khan and Twinkle Khanna
Cascada:Everytime we touch is the best for me. I like a lot of love songs but that one tops it. It seems as a lot of music is directed toward "love" now a days.
Mine is " Tum Se Hi " from Jab We Met. Watch it here: http://www.youtube.com/watch?v=Nk0Oxx4s-8s It is with English subs. Do watch it.
I want to say Young Lust by Pink Floyd but the song that I got laid by, literally, for the first time, was Foreigners' I want to know hat love is" http://www.youtube.com/watch?v=gz2cUX0CNA8
