This difference is that Kim and Missy made classic? Ridiculous to say this because none of us knew they were going to be considered classics when they were out. No one! We don't know that Nicki music in 20 yrs will be considered classics. I'm sure the folks who loves this song will consider it a classic. Also Nicki was huge before Super Bass. Super Bass just helped out. And it doesnt matter how it became popular anyways. Her album is selling very well.
