Thank God.Thanks to freesound.org. I could track the files i downloaded which i used it in my video 2 years ago https://www.youtube.com/watch?v=pIuclYktwY4
Some one claimed the rights for this audio(http://www.cdbaby.com/cd/jeffowens11 Tropical Rainforest) and youtube started showing advertisements suddenly. I disputed this claim by pointing them this location and waiting for their response. Added your name in the credits section. Thanks for the audio!!
