Being a major hit or a large milestone in one's career does not make a song a "classic." A song is deemed a classic based on its own musical qualities, for its enduring appeal over time, not for its commercial impact or sales numbers.
Only one Katy song really has the potential to be considered a "classic" down the line so far into her career and that's "Teenage Dream"
