A 'playback' voice is considered a clean, sweet voice which sounds nice on the mic and fits many actors without the audience noticing a considerable dissonance between the actor and the singing voice. Classic 'playback voices' are Lataji, Rafisaab, Uditji, Sonu, Shaan, KK, Sunidhi, Shreya...
But in the current musical scene, especially in Bollywood, there has been a growing interest in non-typical voices. Take for example Sukhwinder Singh, Mohit Chauhan, Atif Aslam, Rekha Bhardwaj, Kavita Seth, MIka Singh, Salim Merchant, Vishal Dadlani and others with non-'playback' voices who are ruling the charts and giving Hindi music an edge.
This has got to do with a change in the genre of filmi music. MDs draw upon a wider range of musical styles, such as soft rock or sufi (the most popular alternative styles these days) - both of which require 'non playback' voices. Also, there is a decline in lip-synced songs and an increase in background songs - which means that singers' voices need not fit the actors. Take for example 'Tumse Hi' from Jab We Met, 'Masakalli' from Delh-6, or 'Iktara' from Wake Up Sid - these chartbusters were all background songs which weren't lip-synced by actors. And they're not by 'playback' voices.
