The top three most featured Nigerian musician from my own perspective are as follows;

1. TU FACE IDIBIA

An icon in African music who shot to the limelights with his hit song African Queen, has not just featured in almost all the A-list music star's in Nigeria but has also collaborated with unknown and upcoming musicians in Nigeria to encourage them in the industry.

The multiple award winning music star has featured with some of the following music stars; Highlife legend, PA Victor Nwaifor, P Square, Bracket, Joel, Sound Sultan, 9ice just to mention a few,

2. Flavour

The Ada Ada music crooner who has been very active in the music scene has been featured with popular musicians such as Tiwa Savage, Chidinma, Wande co etc

3. Tiwa Savage

This controversial music diva has also featured with many popular and upcoming music stars.

Hope I'm right, if I'm not, prove me wrong.

Tu baba !!!!
