I mistakenly locked this question as part of ongoing depreciation of music id-request. Regardless it should have been closed as opinionated.
This straddles the link in acceptable opinionated questions related to music. You have a 3 second clip with a riff that you presume sample the "Eye of the Tiger" song. The clip sample size provides hardly any evidence to justify that it was sampled, inspired or otherwise copied from the alleged original song. While it's true that there are music thare draw inspiration from other works for effect (as in not a near exact copy of the riff), the evidence you provide does not make this connection or does it explain why you believe it to be so. So in lack of any clear evidence to support your case, the question is based on your subjected assumptions rather than evidently explained facts.
