Music critic Arther Strangeways of "The Observer" first introduced Tagore's songs to non-Bengalis through his book "The Music of Hindustan". The book describes Tagore Song as a "vehicle of a personality ... [that goes] behind this or that system of music to that beauty of sound which all systems put out their hands to seize." Rabindra Sangeet has two great works, which are now national anthems of two countries: India and Bangladesh. This makes Tagore the only person in the world to have written the national anthems of two nations. They are Bangladesh's "Amar Sonaar Baanglaa" and India's "Jana Gana Mana". "Rabindrasangit". They are also influenced by musicians like Vilayat Khan, Buddhadev Dasgupta, and composer Amjad Ali Khan.
