Push and Shove is one of my favorite ND albums, with the title track, "Settle Down," and "Sparkle" songs that I listen to regularly.
I honestly think the problem with the whole album was that No Doubt fans felt it was influenced too much by Gwen's solo pop career, and fans of Gwen's solo career were disappointed it wasn't poppy enough. Also, the "Looking Hot" video debacle did the album promo no favors, and her getting pregnant with Apollo and putting the kibosh on a proper tour also didn't help.
