Sonu still had more hits than shaan and KK during 2006-2009 times , i dont remember any major kk songs besides these few 2 songs Jannat and kya mujye pyar hai and beete lamhe, and khuda jane main fida and tu he mere shab hai , and shaan for hey shona , jabse tere naina , you are my love and don title song,,,,while sonu nigam had Salam e isqh 2 songs both were equally popular the title song and Tenu leke main jawanga which is popular even now for weddings , Garam masala's falak dekhoon , ada both were super hits , Kabhi alvda na kehna , Krish songs , Dil vich lagya ve from chup chup ke , Janeman entire album , from partner duppata tera, Maria maria and sonhi de nakhre and you are my love were rage while sonhi de nakhe , "although according to youtube analysis Maria Maria have the the third most views after Duppata tera, soniye de nakhe and you are my love .. ,,,Do you wanna partner wasnt that big of a song" ,,and the biggest song from the album partner probably is Duppata tera nau rang da by sonu nigam and kunal kanjawala,... 2 hits for Sonu in partner ,,Sonu's Chiggy Wiggy overshadowed any club song back in days and was immensely popular during that time , then had some memorable songs in parinta , jodha akbar also had some good songs 3 idoits, kurbaan, Aja nachle and lage raho muna bahi too specially pal pal pal har pal, and what not till 2009 ,
Sonu had much more impact during 2006-2009 compare to shaan and kk
