How old are the people calling Katy Perry and Taylor Swift songs more iconic than BOMT?
Just because a song sells a lot of copies doesn't make it iconic. To be iconic the song has to break new ground. BOMT changed pop music and steered it in a different direction. It has to be one of those things in pop culture where we all stop and collectively have a moment because we know that some s*** just went down and things will never be the same.
The release of BEYONCE was an iconic moment in pop culture but none of the songs themselves are iconic (yet). The album drop and the album itself are iconic. It's one of those things where you can feel the winds changing.
