Synonyms: 
yaḥ — which; tu — on the other hand; uttamaḥ-śloka — of the Supreme Personality of Godhead, who is praised in transcendental verses; guṇa — of the qualities; anuvādaḥ — the recounting; saṅgīyate — is sung; abhīkṣṇam — always; amaṅgala-ghnaḥ — which destroys everything inauspicious; tam — that; eva — indeed; nityam — regularly; śṛṇuyāt — one should hear; abhīkṣṇam — constantly; kṛṣṇe — unto Lord Kṛṣṇa; amalām — untainted; bhaktim — devotional service; abhīpsamānaḥ — he who desires.
Translation: 
The person who desires pure devotional service to Lord Kṛṣṇa should hear the narrations of Lord Uttamaḥśloka’s glorious qualities, the constant chanting of which destroys everything inauspicious. The devotee should engage in such listening in regular daily assemblies and should also continue his hearing throughout the day.
Purport: 

Since any topic related to Lord Kṛṣṇa is auspicious and transcendental, the direct narration of Lord Kṛṣṇa’s own activities, political and nonpolitical, is certainly the supreme subject matter for hearing. The word nityam here indicates regulated cultivation of the topics of Lord Kṛṣṇa, and abhīkṣṇam indicates constant remembrance of such regulated spiritual experiences.
