I&#x27;d agree on the music part. Timeless is something that stays unique, that will never be replicated. The Beatles have been successfully copied and mass-marketed, and are no longer really timeless. &quot;Smells Like Teen Spirit&quot;, I would argue, is timeless, in that none of the imitators ever really pinned it down. Kids still hear it and it resonates with them. I would pin Queen as timeless as well, nobody has managed to really get that formula right again, but it still appeals today. Comedy can rarely be &#x27;timeless&#x27;, because its SO easy to steal a routine or a persona that made a previous comedian beloved, and thus dilute it.
