Here is my list!
I think RD was one of the phenomenal Music Directors who learnt well from his Father. Even though we see a lot of Western influence in his orchestra, but still he was equally at ease with the slow sentimental numbers.
he was the one who brought the trend of hot-sexy numbers, which is quite visible nowadays as Item numbers in most of the movies. Here is my list of top 20.
AANEWALA PAL JANEWALA
CHURA LIYA HAI TUMNE
DUM MARO DUM
EK LADKI KO DEKHA
HAMEN TUMSE(MALE)
MERA KUCHH SAMAAN
CHINGARI KOI BHADKE
NA KOI UMANG HAI
TERE BINA ZINDAGI SE
RAAT KALI EK KHWAB
NAAM GUM JAYEGA
JIS GALI MEIN TERA GHAR
DO LAFZON KI HAI DIL
O MERE DIL KE CHAIN
KUCHH NA KAHO(HAPPY)
PYAR DIWANA HOTA HAI
CHAND MERA DIL
YEH SHAM MASTANI
HUZUR IS KADAR
MERE NAINA SAWAN(MALE)
