If Joni indeed doesn't sell (TI, TTT and BSN were particularly disappointing, given Joni's '90s return to favour),
I know some people find this subject tedious. But anyway, I think it would be safe to say that TI and BSN had respectable (if far from spectacular) sales, especially TI, which I believe sold over 300,000 copies. BSN probably around 200,000. TTT and T'log have experienced minimal sales, with T'log not even cracking the top 200 (I'm pretty sure), something that hasn't happened since the first album, if even then. It's all about radio, baby. No matter how controversial or odd, T'log would be selling well, if it were only on the radio. Bryan
