The fact that GGGB sold almost as much singles as the TD era before the digital explosion should easily tell you how big of an era GGGB was.
No, it didn't.
In the "TF(M)" vs "TD (TCC)" thread, your fellow stans did an overestimation of 38m WW from GGGB:R singles. TD sold 32m (and likely to sell 2-3 more, at least) just in the US. So, no. It's not even close to TD.
you can't even win in singles.
