Who is/was your favourite male playback singer in bollywood ?

Kishore Kumar remains my all time favourite playback singer in hindi movie industry.
Kishore da's number still remain a big hit and are music to ears, unlike modern day singers.

"Chura liya hai tumne jo dil ko", "Main aashique hoon baharon ka", "Dil kya kare jab kisi ko" are my favourite songs in addition to the Padosan song "Ek chatur naar, badi hoshiyaar".
