srnvata sraddhaya nitya,
grnatas ca sva-cestitam
kalena natidirghena,
bhagavan visate hrdi
Srimad Bhagavatam (2.8.4)

Sri Hari will very soon enter into the hearts of devotees who speak and hear about His Name, Form, Attributes and Pastimes regularly with firm faith. Sri Visvanath Chakravaty says in his commentary that the devotional form smaran, remembrance, is subservient to the devotional forms sravan, listening and kirtan, singing i.e. hearing and singing devotional songs or narrating the glories of the Supreme Lord. Srila Bhakti Siddhanta Saraswati Goswami Thakur has given his remark thus - there is no need of artificially remembering the pastimes of Sri Krishna for the devotees who perform the devotional forms of sravan and kirtan, with submission to Sri Krishna and with the purpose of pleasing Him.

Sri Prahlad Maharaj in Srimad Bhagavatam has said categorically that when the votary performs nine forms of devotion including sravan and kirtan with complete dedication to the Supreme Lord Vishnu and directly for His satisfaction, then this will be the proof of his proper study of scriptures and success in devotion.
