I am not including James Blunt's You're Beautiful as I have not heard that song properly. Also, Chaudahvin Ka Chaand doesn't feature here since am not very much into old songs.
No need to explain anything. She indeed is beautiful & this song seconds that.
Dancepop, massive floor-filling chorus & lyrics that convey the message that yes, she is amazing.
7. Jaane Kaise Shab (Raqeeb) - KK
Meri Aankhon Ko Ye Kaisa Manzar Mila, Tere Har Naksh Mein Bas Khuda Hi Khuda
Don't these lines convey what you feel for her? Comparing her beauty with God is a big deal, but then, didn't God itself gave her that beauty? Right!! And KK singing the song in his usual melodious voice, this one is yet another piece of beauty to appreciate hers! Yes, I prefer lyric-videos more :)
8. Aasman Ke (Humsafar) - KK.
Another KK song here (no wonder why his voice suits this genre so much!)
Aasman Ke Hain Saare Taare, Hai Mera Chaand Kahaan
Need I say more? Chaand and her, enough said ;) Watch the official video with KK singing the song in the video itself.
9. Chehra Hai Ya Chaand Khila Hai - Kishore Kumar.
Yet another comparison with the moon! This one is my personal favorite lyric-wise. This song describes the beauty of face, hair & eyes at the same time. And I so love it.
10. Tumse Accha Kaun Hai - Mohammad Vakeel
Hmm!! Another favorite of mine that compares her beauty with the moon (stars, flowers, dew & what not?)! This one is perhaps the most innocent praise song for her. I really love the emotions conveyed through beautiful Nadeem-Shravan melody, sensible lyrics & soulful vocals. Really Tumse Achha Kaun Hai?? No one ;)
11. Saathiya - Sonu Nigam
Well, this one is a bit odd here. Saathiya praises her ever beautiful smile & really, what's more beautiful than her dazzling smile? I am sure, if you sing this to her, she will blush right-away & start smiling for you :)
"Hansti rahe tu hansti rahe, haya ki laali khilti rahe"
12. Falak Dekhun - Both Versions (Udit Narayan & Sonu Nigam)
"Falak dekhun, zameen dekhun, jahaan dekhun tera chehra, wohin dekhun"
One of the best songs to describe the beauty of a girl. I won't be explaining it in detail since the song itself is so beautiful <3 It describes many aspects of her beauty & all it needs is an honest person singing his heart out to his girl and she will be swept off her feet for sure :-) Beautiful melody, beautiful lyrics & beautiful vocals.
Udit Narayan's version is a slow, down-tempo love ballad with gorgeous melody & typical Udit style all over it.
Sonu Nigam's version is up-tempo, poptastic & more in the vein of a club song. But with Sonu Nigam's voice, you know its always going to be beautiful and with this theme (Songs To Tell Your Love She Is Beautiful), it will be much more special :-)
