Was late Nusrat Fateh Ali Khan a Sufi? Sufis sound like Islamic version of Bhakti.

Yes. Nusrat was. So are the members of the Pakistani band, Junoon.
And the latter part, Sufism is essentially Islam toned down with the Bhakti ideals, atleast in Kashmir, where it helped in the fastest mass conversion to Islam. Practically all castes and classes in Kashmir converted.
Sikhism was an offshoot of this movement, but woke itself up to become one of the most dominant anti-Islam forces within the Mughal-ruled Subcontinent.
