A glimpse video of 'OG' was released on September 2, marking Pawan Kalyan's birthday. A portion of the BGM composed by Thaman has been lifted from a video titled 'Splasher! - Alphagun', Netizens are pointing out.
However, others argue that Thaman didn't copy but has only sampled. What is sampling in music? "In sound and music, sampling is the reuse of a portion (or sample) of a sound recording in another recording. Samples may comprise elements such as rhythm, melody, speech, sound effects or longer portions of music, and may be layered, equalized, sped up or slowed down, repitched, looped, or otherwise manipulated," says Wikipedia.
In the present case, Thaman has only sampled a small part in composing the 'Hungry Cheetah' BGM.
While others like AR Rahman and even Ilaiyaraaja have done sampling in the past, the difference between them and Thaman is that the best part of their music for a song was not the sampled part. On the other hand, the best part is the sampled part in Thaman's songs/scores. That's where the key difference lies and that's why he gets trolled by Netizens.
