It's been 4 years and not a single 4th gen BG has gotten a hit in SK, why?

Many 4th gen ggs have managed to get a hit but not even one bg has gotten one in SK.

What makes 4th gen bgs different to 3rd and 2nd gen?

the general public stopped caring about bgs some years before 4th gen began in 2018

can't hit big regardless of the song if no one is checking you out in the first place
