But that's not the way mainstream radio/media works. In the end, it was worth it because the band was actually thinking of breaking up or seriously reevaluating their career if the album wasn't successful, IIRC (i can't remember if that's in the liner notes or 15 said so on here many years ago)

Because of that album, they were able to get some notoriety, get another gold album in Phrenology, and continue to get probably really good money touring the world.

I do think ?uest said the biggest reason the song/album was a success was that the label basically paid radio to play the song. So, given the number of resources the label was willing to give to the band, maybe the band had to give a little and take Jill off of the song.
