REALLY? I mean I haven't seen any numbers for Mofo or Last Night on Earth, but I sure never heard them even once on the radio......
LNOE charted at about the same place as Boots in the US, if I remember correctly. SATS hit the twenties and Disco hit number ten, but people forgot about both of them pretty quickly (SATS probably had a little more staying power than Disco, and could be considered Pop's biggest hit, but the promotion and final mixing of SATS didn't allow the song to realize its full potential). IGWSHA and Mofo, of course, failed miserably.
A lot of the negative reaction for Pop came after 1997... at least in the US, it got a reasonably positive reaction at first, although Disco stupified most people. I think the botched first night of PopMart hurt the album's legacy as a whole pretty badly.
