The great DEVA RISHI NARADA AND TUMBURU, A CELESTIAL GANDHARVA, had attracted several millions and millions of the Devas through their wonderful music, and it is believed, that even the great Lord Indra and Lord Vishnu, used to specially invite them to their divine worlds, in order to hear the Divine music from their music instruments.
As per legend, the great Vishnu Devotees, Dhruva and Prahalada had got the habit of listening to the music of Narada, since their main Guru was Rishi Narada. When Narada was incarnated as Purandara Dasa, he used to play the Divine music in the palace of Sri Krishna Devarayaru, and during the time of listening to his music, the great king and the people who assembled in the palace, were forgotten about worldly matters, and they have shown their attention only on listening to the divine music of Sri Purandara Dasa.

Big personalities like Churchill and Albert Einstein used to listen to melodious music, and it is believed that during their life time, sometimes they used to play the musical instruments with their own hands.
Listening to good music help us to control our blood pressure levels and from heart attack problems, and also it would control the bad habits like lust, anger and greed, and it helps us to develop good habits like generosity, love and affection, and also we would be boosted with lot of spiritual energy, by listening to lot of bhakti songs in praise of the almighty.
