No. Initiation is required only if you want to do mantra sadhana, not for listening. You just have to listen to the mantras we provide to get benefited.

Om, I bow to Lord Dattatreya, who is pleased merely by remembrance, the remover of great fears, the giver of supreme knowledge, the embodiment of consciousness and bliss, appearing in the form of a child, a madman, or a ghost, the great yogi, the ascetic, the joy-enhancer of Anasuya, the son of Atri. Om, the liberator from bondage, Hreem, the giver of all powers, Krom, the attractor of the impossible, Aim, the bestower of speech, Kleem, the subjugator of the three worlds, Sauh, the agitator of all minds, Shreem, the giver of great prosperity, Glaum, the bestower of sovereignty over the earth, Dram, the one who grants long life. Vashat, subdue! Vaushat, attract! Hum, incite enmity! Phat, drive away! Thah Thah, paralyze! Khem Khem, destroy! Namah, bring success! Svaha, nourish! Cut the effects of all evil mantras, yantras, and bindings. Remove the effects of planets, destroy diseases, remove sorrows, dispel poverty, nourish the body, and satisfy the mind. You are the form of all mantras, the essence of all yantras, the embodiment of all sprouts. Om, I bow to the great Siddha. Svaha
