Android offers a straightforward process for setting custom MP3 files as ringtones:

देखिए वो काली-काली बदलियाँ, ज़ुल्फ़ की घटा चुरा न लें कहीं, चोरी-चोरी आ के शोख़ बिजलियाँ, आपकी अदा चुरा न लें कहीं, यूँ क़दम अकेले ना आगे बढाईये… (Look at those black rain clouds, lest they steal you away with their tresses; The playful lightning may come secretly and steal your grace; Don’t move forward alone like this...)
