Who amongst the following is not singer-music director?

Javed Ali is primarily known as a playback singer and not as a singer-music director combination. While he has sung numerous popular songs in Bollywood and other industries, he does not compose music himself. In contrast, Adnan Sami, Mithun (likely referring to a composer-singer), and Vishal Dadlani are all known for both singing and composing music. Vishal Dadlani is particularly famous as part of the Vishal-Shekhar composer duo while also being a vocalist.
