The song you're likely thinking of is "Tamilgun" or more specifically, "Telugu Gun" but I found it as "Tamilgun" which seems an unofficial/release version.
The word "exclusive" is a powerful psychological trigger. It suggests that Tamilgun has a special copy that even legitimate platforms don't possess. In reality, this is often a misnomer. It might be a slightly cleaned-up version of an HD rip from a foreign streaming service or a re-encoded print. But for the desperate viewer, the promise of an "exclusive" is enough to risk clicking. ala vaikunthapurramuloo tamilgun exclusive
